West Coast leaders are recognizing the opportunity to capitalize on the national push for green jobs and alternative energy. This plan will put them in position for a portion of the $15 billion in federal stimulus dollars allotted to alternative energy development. All three states are working together to make this plan a reality.  Washington State is ready to start implementing the plan as soon as this summer, with additional plans to build refueling stations at Park and Ride locations.

As expected there are already companies jockeying for potentially lucrative contracts to install these refueling stations in major cities and rest stops. One of these is Better Place, led by Shai Agassi a former Silicon Valley software exec. His company has already built automated electric car charging and battery swap stations in Israel and is expanding to the SF Bay Area, Hawaii, Canada,  Japan, and Australia. Washington’s Governor Christine Gregoire has already met with the innovative business owner to discuss the plan. As of yet no contracts have been awarded.

This idea is causing a ruckus with interest groups like the National Association of Truck Stop Operators that claim state approved rest station fueling facilities would compete with truck stops, gas stations, hotels and restaurants. This claim seems outlandish considering that the people in need of the alternative refueling stations have little or no options currently. Due to the lack of private investment in the alternative fuel sector the government sees an opportunity to incubate private infrastructure investment in these emerging alternative fuel technologies. As outlined in the WSDOT Alternative Fuels Corridor Pilot Project, they will avoid hosting refueling sites in geographic areas where existing businesses already provide sales of alternative fuels and will help to promote existing businesses throughout the I-5 corridor.

It would make sense for the truck stops and gas stations to take the initiative and provide these service to a new customer base, rather than trying to derail a legitimate plan to encourage private investment in alternative fuels, create green jobs, cut greenhouse gasses and reduce the nations need for foreign oil. Its ridiculous for these interest groups opposed to the plan to attempt to stake a claim on a customer base they don’t serve. Encouraging innovation and new technology is what will allow us to thrive as a nation and as a world for decades to come.

If you build it they will come!

Selling power back to your utility company can be easy. Essentially you use a solar or wind powered source for energy during the day and it supplies energy back to a grid, causing your utility meter to run backwards.

Then, when it is dark outside or windy, the meter starts to roll forward again. This helps to save hundreds or thousands of dollars each year in electrical bills.

Before you can start to use this type of system, you must contact your local utility company and file an interconnection agreement with them. This gives you the rights and regulations you have to abide by in order to use your solar or wind powered source for energy.

Currently over 40 states have laws in affect stating utility companies must allow some kind of interconnection agreement with its users. Most utilities companies will not mail you a check if you produce more energy than they do.

But, they may agree to roll over the dollar amount you saved towards the next month or a future month when you experience more usage. The government has recently started giving tax breaks to those using solar or wind power as electricity, giving them another great chance to save money.

The problem many people are encountering is solar powering is not stable. With a grid, solar power is transferred into energy. In most cases, only 10 to 15 percent of solar power has the ability to be transferred into use-able energy for sustaining a household.

The world is an energy devouring place and we need to be exploring greener sources of energy to furnish that demand. We also need to see better ways of using the current green energy technology that are already in place. We all need to be interested about the impact that is being placed on our planet and how the high cost of energy is affecting us. The energy that is wasted every day is a sad state of affairs and everyone should take a look at what they could do to be more moderate in their usage. The energy that is wasted every day is a sad state of affairs and everyone should take a look at what they could do to be more cautious in their use. There are solutions to these issues but how inclined have people been to fulfil these solutions at the present.

Wind power has started to become very popular over the last decade as a very real source of renewable energy. The price of the power it creates is becoming very aggressive with established methods of energy production such as coal and natural gas. Power used to be created by windmills in the past on the family farm for many years. The agricultural landscape used to be scattered with them to supply power to pump water. It is a identified fact that the states of Texas, Kansas, and North Dakota have sufficient wind to furnish power for the whole U.S.

Another renewable enegy source that has gotten much press is corn. The ethanol that is formulated from corn is a clean burning energy source and crops can be grown year after year so it is inexhaustible but at what cost. The cost of corn has gone up as the result of this, which is good for the farmer but bad for the consumer. Research has shown that praire grass would do a better job than corn. In reality it generates more energy per acre than corn. Plus you don’t have to cultivate it because it grows wild. It is a chemical free crop that just needs to harvested and processed.

Another renewable enegy source we see and hear more of is solar power. You have the solar panels which convert sunlight into electricity and solar water heater to produce hot water. I’ve read about people who have placed solar energy systems on their homes in areas you wouldn’t think it would work, like Seattle. The payback figures for the system were impressive even for a mostly overcast area like this.

One of the things I like about solar is that it can give the power back into the peoples hands to a large degree. The control of power can be decentralized. Maybe that is one of the reasons why there hasn’t been as much advancement as there should be and why costs remain high. Corporations want to protect their profits and it almost seems they do anything to make that happen.

We all know that oil isn’t going to last forever. If we don’t start doing something about it now than when. Aggressive measure need to be taken to start setting in place and implementing a new energy infrastructure. We can start to benefit from it now but we also need to think of how it is going to be of value to the next generation. Help out by doing something to make renewable energy something we can all enjoy.

You can learn more about solar chargers, wind turbines , and other forms of renewable energy sources by doing more research on the Internet about the subject that interests you the most.

Efficient Lighting liteLogix designs and markets energy efficient lighting systems for Municipalities, Educational Facilities, Health Care Facilities, Retail Facilities, Commercial Facilities, and Industrial Facilities.

There are predominantly two types of solar power generation methods used to create electricity on a commercial scale. Photovoltaic panels, which are the large collections of the systems that you see in small scale on house roofs. Concentrating solar power (CSP) uses thermal solar power, the heat of the sun, to produce environmentally friendly energy.

We will take a look at the way in which concentrating solar power plants create electricity. CSP plants are capable of producing electricity at a higher maximum capacity than a photovoltaic facility of the same size. They will play an increasingly important role in the move away from fossil-fuel sourced energy to that of renewable energy.

The four main commercially productive concentrating solar power systems are: parabolic troughs, fresnel reflectors, dish / engine systems and central receiver systems. Each of these technologies have been proven and are currently in operation around the world with more developments in solar power in progress to try to meet future demands.

Parabolic troughs use mirrors to direct sunlight onto a fluid-filled receiver positioned in directly in front of each trough. The heat generated from this process heats the fluid to high levels so that super-charged steam is generated. Electricity is then created by means of a conventional steam generator.

A trough-based CSP plant typically consists of rows of mirrored troughs placed parallel to each other along a north-south axis in what is known as a collector field. Optimum heat exposure is maintained thanks to the pivoting nature of the parabolic troughs which track the sun’s movement across the sky. Electricity continues to get generated when the sun is not around thanks to thermal storage. Technological advancements are continuing to prolong this production period in a bid to move to continuous solar electricity production.

One of the largest developments to use the parabolic trough design is the Andasol project in Spain. The surface area of the mirrors used to form the energy collection field of Andasol 3 alone is around 500,000m2.

Fresnel reflectors are similar to parabolic troughs except they are flat mirrors that focus light onto one receiver. Costs are reduced using this method because the rows are positioned more closely together, there are fewer moving parts and less receivers are required. The receiver is stationary and it is shared by multiple mirrors.

An example of a recently commissioned CSP plant using reflector technology is the Kimberlina CSP plant in California developed by Ausra. This power plant is relatively small at only 5MW capacity, but it paves the way for future large-scale developments.

Dish / engine systems are stand-alone units that contain dish-shaped parabolic mirrors that concentrate the suns energy onto a receiver mounted above the dish. The receiver takes the energy and converts it into heat which is then converted into mechanical power, similar to a mechanical engine. Each dish / engine unit has a capacity of around 25kW of solar power and it tracks the sun to ensure optimum power.

An example of the dish / engine technology is the Stirling Energy Systems dish called the Suncatcher. It will be used in fields of thousands to form a power facility capable of generating over 500MW of electricity.

Central receiver systems are also known as power towers. Looking as though they’re honoring a higher deity, thousands of mirrors called heliostats cluster around a receiver that sits on top of a tall tower. The heat that is collected by the receiver then heats molten salt as it flows through which is then used to make steam that operates a conventional steam generator. The molten salt can be stored for great lengths of time which means that this type of solar energy generates electricity continuously around the clock.

An example of a central receiver system in development is the Solar Tres power plant being built in Spain. The Solar Tres power plant will be a 15MW facility and it follows on from the successful demonstration power plant known as Solar Two which was located in the Mojave Desert.

As technological advancements continue to be made, the critical factor of the cost to produce each watt is gradually being addressed. Already, concentrating solar power plants hold a huge advantage over the traditional fossil fueled counterparts in the lower impact to the environment. In fact, one of the only impacts that concentrating solar power plants have on the environment is land use.

Renewable energy continues to grow and with continued support it will eventually become one of the main sources of electricity around the world. Concentrating solar power has proven to be a renewable energy source with still more untapped potential

Making use of the natural heat from the earth, geothermal energy is a growing force as a source of renewable energy. It has already been used to provide power to 1.2 million homes in the United States. It has far greater potential and to both heat and provide electricity to homes and is yet to be properly utilized. That’s about to change.

Geothermal energy comes from a variety of sources of heat within the earth: decay of naturally occurring substances within the crust, the earth’s core and movement of continental plates as they slide against and underneath each other. Volcanoes, hot springs and steam vents represent the easily accessible points to this energy but most geothermal energy is trapped under the earths crust and must be accessed by drilling into the resource and harnessing the energy. The thermal energy in the uppermost 6 miles of the earths crust contains 50,000 times the energy of all the worlds gas and oil resources.

What Is Geothermal Energy?

Geothermal energy is the heat stored under the earths surface. In some parts of the world where the earths surface is thin or cracked, steam and molten rock can escape. These are usually locations of high seismic activity such as earthquakes and volcanoes. If water finds its way into these cracks, it becomes heated and may come to the surface as geysers, fumaroles, hot springs and mud pots.

Parts of New Zealand, Japan, USA and Europe have high geothermal activity. High grade geothermal energy such as geysers, hot dry rocks, mud pots and fumaroles is used to generate electricity. Geothermal energy can also be used as a heating source, for example in Iceland hot water is brought to the surface through a bore , then sent through insulated pipes into homes and radiator panels which provide heat. Over 80% of homes in Iceland are heated this way.

Although geothermal energy doesnt pollute the air with greenhouse gases, there are other environmental concerns about its use. Scientists are not sure how the long-term use of this resource could affect our underground water supplies. Some geothermal tourist attractions at Rotorua in New Zealand have already suffered a decline in surface activity due to the draw-off of geothermal fluid from the underground reservoir by domestic and commercial uses.

Geothermal energy can be broken down into 4 main types Geothermal energy can be broken down into 4 main types geopressured, magma, hydrothermal and hot dry rock.

Hydrothermal

This is the only type of geothermal energy that is currently producing commercial quantities of electricity and is derived from hot water and steam formed in porous or fractured rock at relatively moderate depths from 100 metres to 5 kilometres.

The hot water and steam come from the intrusion of molten magma into the earths crust or the deep circulation and heating of groundwater through faults and fractures.

To generate electricity, hot water at temperatures ranging from 180 250 degrees Celsius is brought from the underground reservoir to the surface through production wells and is flashed to steam in special vessels by release of pressure. The steam is separated from the liquid and fed into a turbine engine which turns a generator. Spent geothermal water is returned back to the reservoir to help maintain reservoir pressure.

Geopressured

Geopressured energy is derived from hot, pressurised waters containing dissolved methane, trapped at depths of three to six kilometres in sedimentary formations. The water temperature ranges from 90C to 200C.

Three forms of energy can be captured from geopressured sources chemical energy from burning the dissolved methane, hydraulic energy from the high pressure, and thermal energy from the hot water.

Hot Dry Rock

Under certain conditions granite at a depth of 3 to 5 kilometers under the ground can get to 250C. Unlike hydrothermal resources, the fractures and faults required to conduct water to the surface are not present, therefore water must be pumped into the rock at high pressure to create an artificial underground reservoir of steam or hot water.

A number of development projects continue into attempting to make use of hot dry rock to create electricity but factors such as cost and questions about resistance of the reservoir to flow, water loss and thermal drawdown remain. Costs are coming down though and geothermal technology in general will improve enough to make hot dry rock economically feasible.

Magma

Magma is the molten or partially molten rock that is found at depths between three and 10 kilometres beneath the Earths crust and reaches temperatures up to 1200C. While some magma resources are at accessible depths, a practical means of extracting energy directly from magma has yet to be developed, instead magma is used indirectly by exploiting the water it has heated. Magma is only accessible where volcanic activity or tectonic plate movement occurs.

The Future Prospect of Geothermal Energy in the US

An exciting new development in the future of geothermal energy in the United States has just been announced by the Department of the Interior who have promised to make 190 million acres of federal land available for geothermal power development. This is good news because the proposed land includes no environmentally sensitive areas such as national parks or designated wilderness areas.

By the year 2015 it is estimated that electricity from geothermal power production in the United States can reach 5,500 MW thanks to this new initiative. Its a positive move that will promote a form of renewable energy that has been used for years, but perhaps not to its full potential.

With every hike in the price of electricity, more and more people are thinking about using renewable energy for at least part of their regular supply.

What type of renewable energy you decide to use will likely be decided by whereabouts you live. If you enjoy a reasonable climate and the sun shines for much of the year, you’ll likely decide to use solar energy.

If you live in chillier climates, chances are that your thoughts will turn to using the power of the wind instead.

Each of these has advantages and disadvantages.

Pretty obviously, solar power only works in daylight, even if the efficiency of modern solar cells means the sun can be hidden from view. If you’re in a hot area, the sun will be shining at the time you most need your power for air conditioning and other such items. In cooler climates, solar power almost certainly won’t be your only option, although it would still contribute to (say) heating your pool in the summer or providing extra light in your garden for those evenings where it isn’t too chilly to stay outside.

Wind power needs some kind of wind but they’ll also have an upper limit of windspeed, beyond which they won’t operate – if the wind falls below a certain speed, they won’t operate, if it blows too fast the turbine may struggle to keep up. You also need to remember that even in the most windy places, there are times of dead calm, so you’ll need a battery or regular power connection for such times. This problem also means that unless you have your own storage, you shouldn’t totally go off grid power if you rely on wind.

Your next choice is whether to have your renewable energy system professionally installed or to give the DIY option a try. You can get a set of comprehensive renewable energy instructions to help take you down this path if you like, with the added advantage that you’ll be saving hundreds of dollars if you go down the DIY renewable energy path.

The availability of alternative energy comes in many different forms. One of these is solar power: Solar power is driven by photovoltaic cells, and these are progressively getting less expensive and more advanced.

There aren’t any areas where solar power cannot be utilised including: generating electricity and hot water plus of course it has the added benefit of being pollution free. However, much more work still needs to be done in order for us to economically harness the sun’s energy. The one major problem is storing the power for use when the sun is not as strong, on overcast days and when night falls.

As of the moment, the most-invested-in alternative energy source favored by many private investors as well as the government is the wind energy. Huge double and triple bladed windmills can be seen around the world, working constantly, day and night to produce large amounts of electricity. Of course, there is nothing new about the concept of a windmill for harnessing energy.

The windmills used today are massive compared to those used in the past and much more ‘high-tech’ and often referred to as ‘wind-turbines’. The only downside to this form of power is when the wind isn’t blowing, you cannot produce power. Of course, the power we need can come from other sources when this happens so currently we cannot rely completely on wind power even if we had sufficient farms to cater for our needs.

A massive quantity of power can be obtained from another source of alternative energy which is the hydroelectric energy. All that is required is a large body of water and gravity – this fall of water from a great height is able to turn large turbines which generate electrical power. As water is everywhere it has not generally been a problem finding locations where it can be employed.

The main problem with this process is the initial financial cost and the size of these dams means it is a lengthy project which does not come without it’s own issues. Building of dams is often the most common and effective means of controlling the flow of water to sufficiently provide the source in generating the needed power.

Conservationists are starting to be worried about operating a dam as it not only requires a lot of labour building it to store and control water’s potential and kinetic energy but it can also be risky and complicated. To produce power this way does not always require a dam, especially if it is only a small community that is being serviced.

There are other options that you may use especially if it is just to supply neighbourhoods or an individual office or home such as small run-of-river hydroelectric converters.

However, the most underused and under-rated form of energy is geo-thermal: this is the heat which is generated inside the planet beneath the crust. The earth’s inner molten core is the one responsible for transferring the heat into the water.

Power plants use a number of ways to draw this water to the surface and harness it into ‘free’ energy. When hot water is drawn up, it simply means that there is the need to gather steam. The Geysers is an example of a dry stream plant located in the region of about 100 miles north of San Francisco and perhaps the best-known of all geothermal power fields.

Fossil fuels like coal, gas and oil are a finite resource. As it becomes more difficult to detect and extract from the earth, the costs to the consumer are sure to rise. This trend will continue if more resources continue to be used. And this is not the only cost of using fossil fuels. Many people feel that they have caused many of the environmental problems that we are beginning to witness today and ultimately will be paid for by future generations. So what are the alternatives to these traditional sources of energy. This article will cover a few of the alternative energy sources that are being touted as practical solutions both commercially and for the individual homeowner.

The first alternative energy source to be covered is solar energy. It has been with us for a good number of years now and many people are familiar with the odd solar panel in the neighborhood. To this extent, mankind has always known about the Sun’s energy and used it is one way or another since the first civilizations where established, however it is only fairly recently that it has advanced to the stage that we are at now.

At this point in time, the Sun’s heat and light energy is utilized to make energy for consumption.

Heat energy provided by the sun is used for many things like heating water, heating a room or cooking food. The heat from the Sun can be felt on the skin so it was not such a leap of imagination to apply it’s power to other applications. In reality, the Sun was used by many of these civilizations not only as an energy resource but also as a god, indicating the importance that they gave it.

Getting energy out of sunlight is still a fairly new development by comparison. The innovation that makes this occur is the photovoltaic (PV) cell. It was first used in the 19th century but only started being produced commercially in the 1970′s.

The principle behind it is that photons in sunlight hit the PV cell causing an electron to be displaced from the atom. Many cells and more sunlight cause more electrons to flow. This is how direct current (DC) electricity works. Direct current can be stored in a battery or used to power appliances that run on DC.

Wind power is another source of renewable energy that is becoming popular. I think this is because it is fairly well understood by most people as a concept. It may also be because plenty of wind turbines are popping up all over the countryside.

A wind turbine is a modern day windmill, it uses the power of the wind to turn blades. The kinetic energy turns a generator that, in turn, creates electricity. Countries such as Germany, Denmark and the United States are increasing the number of wind turbines every year. They represent a clean and cheap way to create energy.

Wind turbines or windmills can even be built in residential homes at a reasonable cost. It is quite simple to build a windmill or turbine from scratch or a pre-built variety can be purchased. Before you even think about this however, you need to establish if there is enough wind to make it viable and locate a good spot in your yard for it to go. You may also want to notify your neighbors that you are erecting a turbine as it could be an issue with some people.

Other renewable energy systems utilize the kinetic energy of water to create electricity. This is hydro-power and a dam is an obvious example of this process in action. Geothermal energy can also be used to some extent. The idea behind this is to use the heat found in the earth core to heat water, much like a hot spring or spa, to use as it is or as an input to a generator.

Although it is much less expensive to initially get hooked into the local electric company’s grid than it is to set up and hook into wind turbines, in the long run one saves money by utilizing the wind for one’s energy needs—while also becoming more independent. Not receiving an electric bill while enjoying the advantages of the modern electrically-driven lifestyle is a wondrous feeling.

Electric bills and fuel bills are rising steadily—but the cost of wind turbine energy is zero, and the cost of installing and hooking up a turbine is steadily coming down as demand rises and more commercial success is realized by various companies producing the turbines and researching technologies to make them ever more efficient. In addition, people are moving away from the traditional electric grids and the fossil fuels for personal reasons including desire for greater independence, the desire to live remotely or rurally without having to “go primitive”, political concerns such as fears of terrorist strikes on oil fields or power grids, or concerns about the environment.

Again, this motivation to get away from the traditional energy sources is the same one that causes people to seek the power of the wind for their energy, giving more business opportunities to profit from wind turbine production and maintenance, which drives their costs down for the consumers. In nearly thirty states at the time of this writing, homeowners who remain on the grid but who still choose to use wind energy (or other alternative forms) are eligible for rebates or tax breaks from the state governments that end up paying for as much as 50% of their total “green” energy systems’ costs.

In addition, there are 35 states at the time of this writing where these homeowners are allowed to sell their excess energy back to the power company under what are called “net metering laws”. The rates that they are being paid by the local power companies for this energy are standard retail rates—in other words, the homeowners are actually profiting from their own energy production.

Some federal lawmakers are pushing to get the federal government to mandate these tax breaks and other wind power incentives in all 50 states. Japan and Germany already have national incentive programs in place. However, “A lot of this is handled regionally by state law. There wouldn’t really be a role for the federal government,” the Energy Department’s Craig Stevens says.

And as might be imagined, there are power companies who feel that it’s unfair that they should have to pay retail rates to private individuals. “We should [only have to] pay you the wholesale rate for … your electricity,” according to Bruce Bowen, Pacific Gas & Electric’s director of regulatory policy. However, the companies seem to be more worried about losing short term profits than about the benefits, especially in the long run, of the increased use of wind turbines or wind farms. Head of the Center for Energy Efficiency and Renewable Technologies of California V. John White points out, “It’s quality power that strengthens the grid.”

Today, the Worldwatch Institute published an article detailing a decline in offshore drilling opposition in sharp contrast to the year 1982 when the drilling moratorium was enacted. Further expansions by George H. W. Bush in 1990 extended the moratorium to include the coasts of Florida, California and New England. With the presidency of Clinton in 1998, the ban was again extended until the year 2012.

During this time, the United States government has went as far as to buy back drilling leases off the coasts of Florida from such companies as Chevron, Conoco, and Murphy. In 2002, the Bush Administration paid $115 million to these companies to drop the offshore claims they held at the request of Florida Governor Jeb Bush. Further settlements were proposed to entities such as the Collier family to relinquish mineral rights held in the Everglades. The government offered $350 million in tax deductions and $120 million in cash for mineral rights that the National Park Services and Department of Interior estimated at $20 million and $43 million, respectively. Besides, opening a few areas within the Gulf of Mexico in 2006, expansion of offshore drilling leases has been mostly stagnant.

Recent oil prices and focus on acquiring less foreign oil has begun to change the consensus on expansion of U.S. offshore drilling. Reports by Rasmussen show that 67% of voters favor offshore drilling while 64% feel more drilling will lower high gas prices. It seems clear to why the majority of Americans now support an increase in offshore drilling. Effects on the pocketbook speak very loudly, but this is not the only reason for the change in attitude towards the long held view of offshore drilling, being environmentally unfriendly.

Lumped alongside the bill to lift the offshore drilling ban, are a few healthy nuggets of environmental stewardship. Consumer tax credits for fuel-efficient and clean energy vehicles, renewable energy tax credits, development of alternative fuel sources, and mass transit funding are just a few of the environmental benefits outlined in a plan that many hope will see a vote during this year’s session. Though most environmental groups still oppose lifting the offshore drilling ban, many feel the added benefits are so beneficial to providing clean energy and healthy environment, that a compromise can be made. If a vote is not exercised before the conclusion of Congress this fall, any decision will be left till next year while also including the next President of the United States.

Though Republicans do not feel the Democrats’ plan goes far enough to expand new energy sources, past attitudes of “no new leases”, has swayed with restrictions requiring current leases be explored further, and the added tax incentives for renewable energy energy sources. Safer drilling practices, higher oil prices, and increased pressure on providing an energy independent America, may soon make new offshore drilling a reality along thousands of acres of U.S. coastline.

The New York Times has published an article on an aging power grid and the potential setbacks to wind energy and other sources of renewable energy.

Current electric transmission lines are not able to handle the load produced my massive wind farms such as the Maple Ridge Wind Farm in New York.  The 200 turbine strong wind farm, is being forced to shut down production at times to cope with fees that are associated with pumping too much electrical current into the power grid.  This bottle neck is limiting the advances of wind power and is one of the major drawbacks slowing down the implementation of a nation wide renewable energy grid. 

While wind turbines located in places like the Mid-West can generate much more power than the same turbines placed on the east coast, there is not yet a reliable way of transmitting the electricity needed across many states.  Since control of power grids is generally left to state governments, there is little incentive to provide better transmission to out-of-state facilities.  Within each state, transmission lines may be owned by many different companies, causing any upgrades to be a painstaking process.  The Energy Policy Act of 2005 allowed the U.S. government to extend approval of transmission lines in the event that states are not providing upgrades and maintenance, through this has led to little direct expansion and infrastructure upgrades, especially in relation to peak supplies of inconsistent energy sources such as wind power.

The issue of transmitting electricity throughout the United States is something that must be recognized and remedied before further goals of expanding our renewable energy base can be implemented further.  The problems facing the aging power grid are by no means new.  In 2001, North American Electric Reliability Council, was advising congress on the problems facing the current power infrastructure.  Seven years later we are still facing the same concerns but on a much larger scale.  Incentives for renewable energy are great, but the United States must realize that it means nothing if transporting electricity can not be carried out in an efficient, reliable manner.

Companies such as MidAmerican Energy, which happens to lead the country in generation of wind power, and American Electric Power are making steps to help improve transmission lines that will carry some of the renewable energy that is generated throughout the U.S.  This proposal shows that energy companies have something to gain by working together to transmit the power that they are producing.  Without partnerships like these, future renewable energy projects can not proceed at a profitable level. 

While, further development in technologies such as Compressed Air Energy Storage (CAES) and fuel cells, may allow temporary storage of electricity generated by renewable energy sources, transporting energy from state to state is still a needed upgrade to contend with the U.S. goal of energy independence.

The green slime or pond scum that comes from algae could be valuable after all. Renewable Energy Group of Ames says it has developed a process that takes the oil from algae and turns it into biodiesel fuel.

“Algae oil would give us a third option as a biodiesel feedstock after soybean oil and animal fats,” said Daniel Oh, chief operating officer of Renewable Energy Group.

That would be a breakthrough of seismic proportions for the biodiesel industry. The soybean oil that has been the basic oil feedstock for biodiesel has doubled in price in the last 18 months, robbing operating biodiesel plants of their profitability and forcing shutdowns or delays at other facilities.

Researchers around the nation are trying to skim energy from algae.

“People who have made fun of green slime and pond scum won’t do it in the future, when they find out not only how valuable the oil is but also the byproducts,” said Jimmy Simpson, an algae researcher at Maharishi University of Management in Fairfield…….

Mega search engine Google.com, today announced an investment of $10.25 million in advancing the development of green technologies. Google is supporting a technology called, Enhanced Geothermal Systems, to help meet its goal of providing enough green energy to power a city the size of San Francisco. Through Google’s philanthropic entity Google.org, an initiative dubbed “Renewable Energy Cheaper than Coal” has been laid out to make this goal a reality.

Enhanced Geothermal Systems generates energy by pumping cool water 2-3 miles into a reservoir lying on top of dry, hot basement rock. The water is then pumped back to the surface at which point in condenses and creates powerful steam that is used to propel turbines. After the steam cools, it is re-injected back into the reservoir to begin the process again. This process allows energy extraction in areas that do not have natural steam pockets and hot flowing water.

The investments pledged by Google will go to help fund 2 companies and a university working on the development of Enhanced Geothermal Systems. $6.25 million will go to AltaRock Energy, Inc, which will work to reduce the cost and efficiency of EGS technology. Potter Drilling, Inc. has been given $4 million to design drilling tools capable of penetrating deeper and stronger rock. Southern Methodist University Geothermal Lab has been awarded a $489,521 grant to update geothermal maps and study geothermal resources in North America.

Google has recently been involved in many steps to reduce its environmental footprint and promote green technology. Data centers housing Google servers, are being designed to cut the energy needed for cooling to 50% of similar installations. The idea is not only to save money, but to create a self sufficient business model that promotes clean energy. This initiative is evident in the production of a 1.6 megawatt solar energy plant in Mountain View, California. Other projects include the Climate Savers Computing Initiative to create more efficient computers and servers, and the RechargeIT initiative aimed at developing electric vehicles and infrastructure.

Though $10.25 million may seem like a small amount to a power house company like Google, it shows considerable attention is being provided to changing the way we look at natural resources and energy generation. Google has the resources and intelligence to begin to leave a legacy that varies far from just creating one of the most popular websites of all time. Funding and support by Google leaders will help to attract more corporations with the potential for a green technology revolution. Though energy change falls on the hands of every citizen, major projects can not be completed without the funding and backing of large groups such as Google.
