Biofuels have been around as long as cars have.

A biofuel is a fuel that contains energy from geologically recent carbon fixation. These fuels are produced from living organisms.

Generating Electricity from Wing Waves.

Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind.

Producing electricity from solar energy.

Solar energy is a free, inexhaustible resource, yet harnessing it is a relatively new idea. The ability to use solar power for heat was the first discovery.

Turbines catch the wind's energy with their propeller-like blades.

A blade acts much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade.

Solar energy may have had great potential

Solar technology advanced to roughly its present design in 1908 when William J. Bailey of the Carnegie Steel Company invented a collector with an insulated box and copper coils.

We have been harnessing the wind's energy for hundreds of years.

For utility-scale sources of wind energy, a large number of wind turbines are usually built close together to form awind plant.

Biofuels are produced from living organisms.

In order to be considered a biofuel the fuel must contain over 80 percent renewable materials.

Geothermal energy is the heat from the Earth.

Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma.

Geothermal heat pumps can tap into this resource to heat and cool buildings.

A geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building.

In the future, civilization will be forced to research and develop alternative energy sources.

Possession of surplus energy is, of course, a requisite for any kind of civilization, for if man possesses merely the energy of his own muscles, he must expend all his strength - mental and physical - to obtain the bare necessities of life.

Opinion David Cameron And Shale Gas

Opinion David Cameron And Shale Gas
"By Anders Lorenzen"

It seems the UK Prime Minister David Cameron is finally giving in to the anti-wind power and the pro-fracking part of his party, lead by Chancellor George Osborne, as the fracking debate is getting hotter.

With recent remarks stated by Cameron that Britain can't afford to miss out on shale gas, and communities just have to bear the brunt, while at the same time attacking wind power. Cameron advocates that no more onshore wind turbines should be built in the UK, and delivers a complete u-turn from his previous statements. He is also going against what the majority of analysts are saying that shale gas won't lower energy bills, he insists they will.

As the row is escalating, embarrassing remarks were made by Lord Howell, saying that fracking should only take place in the desolate North East (he later corrected that to North West), Cameron has seen it necessary to take the promotion of shale gas into his own hands, something that so far has been left to George Osborne.

Meanwhile Labour (the opposition party, in case anyone had forgotten) are completely quiet on the issue of fracking, letting anti-fracking campaigners guess that they might support it. It's remarkable, since the fracking debate really flared up around three weeks ago, when protesters were gathering in the Balcombe, West Sussex to protest against Cuadrilla's move to drill for oil, Labour stayed in the background. Labour are losing popularity, at a time where they ought to to extend their lead over the Tories. Labour could, with a strong statement against fracking, regain the lead they had on the Tories as they would no doubt capture a stream of new supporters; many of them fleeing from Conservative constituencies threatened by fracking.

Cameron needs to get away from the fantasy that fracking would lead to lower energy prices and stop using the US as an example. He should know that the gas market on the other side of the Atlantic is different than in Europe. Even if the UK was to extract large amounts of cheap gas from fracking, it would not lead to cheaper energy bills, as UK gas prices are based on the European market. If suddenly the whole of Europe started to frack like there was no tomorrow and surge of gas was extracted, then it might, but that's extremely unlikely. As I have previously written, apart from the UK, Poland is the only country European where fracking is taking place, but even there investors are fleeing. Editor of Business Green, James Murray, makes the point perfectly in a recent published letter to David Cameron, asking how his shale gas plans would work as he has not given any details on that matter.

The public are being misguided to believe that we need fracking to keep the lights on, but that simply is not true. By dealing with energy efficiency and upgrading an ageing grid, we could quite likely recoup the shale gas bonanza advocates are dreaming about. By fully relishing our renewable energy potential that we have in the UK, and still remains largely untapped, we could go a long way towards becoming energy independent in renewable energy. Again it's simply extraordinary to say that we should not build anymore onshore wind turbines to protect communities (even though in those communities only a minority are opposed to it) and then on the other hand impose fracking rigs in communities where the majority are against it. Instead of handing out large tax breaks to shale gas companies, the government could hand out tax breaks, for instance, to the UK's promising wave and tidal industry to really get that industry off the ground. But instead this government who refuses to invest in new and modern renewable technologies are locking themselves further and further into the old fashioned fossil fuel industry, trying to suck the very last drop out of fossil fuels that we all know will eventually run out.

Developer Wont Build Controversial Solar Plant Without Tax Incentives

Developer Wont Build Controversial Solar Plant Without Tax Incentives
The controversial Palen Solar Electric Generating System, which was put on hold in November, will stay on hold unless a federal tax credit for building solar power plants is extended.

That's according to Santiago Seage, chief executive of the Spanish-owned Abengoa Solar, which owns the embattled project. Seage told the trade journal Recharge News that without an extension of the federal Investment Tax Credit for solar plants, his company won't have the security it needs to invest in building the project.

Seage made the remarks at the ribbon-cutting of his company's 280-megawatt Mojave Solar plant near Hinkley.

The looming expiration of the 30 percent investment tax credit, set to run out at the end of 2016, is one of the reasons Abengoa and its then-partner BrightSource Energy pulled the ever-changing Palen project off the table in November. Delay fueled by criticism of the plant's likely effect on wildlife, especially migrating birds, as well as the impact on local cultural resources, had caused the developers to miss one funding deadline after another.

By November 2014, it was clear that getting the plant built and operating in time to meet the December 31, 2016 deadline for the tax credit was unlikely. BrightSource and Abengoa withdrew the plant from consideration, and Abengoa agreed that it would buy out BrightSource's interest in the project.

BrightSource has staked its corporate fate on the success of its proprietary solar power tower technology, which uses thousands of independently targetable mirrors to aim solar energy at receivers atop power towers. Its former partner in Palen, though, has no such restriction: Abengoa owns and operates plants using the competing parabolic trough solar thermal technology (as in the recently dedicated Mojave Solar project), as well as the increasingly dominant photovoltaic panels.

When BrightSource pulled out of Palen in November, many observers (Rewire included) suggested that Abengoa might switch strategies and redesign Palen as a parabolic trough plant. After all, that's the design the California Energy Commission originally approved for the plant in 2010, back before the original developer Solar Millennium went belly-up and sold out to BrightSource.

But if you take Seage at his word, Abengoa remains committed to power tower technology for Palen, as well as other projects throughout the desert Southwest. According to Desert Sun reporter Sammy Roth, Seage expects that most of Abengoa's new concentrating solar projects will use power tower technology due to the claimed ease of incorporating power storage into plants of that design.

"We expect that going forward, most if not all concentrating solar plants in the Southwest will include storage," Seage told Roth.

The likelihood that Congress will vote to extend the Investment Tax Credit, or to alter its language so that projects need merely break ground by the deadline rather than generating power, isn't clear in the wake of the Republican capture of both houses. Unlike wind power, whose growth in red states means a significant Republican pro-wind constituency, solar power doesn't seem to have much of a fan base among conservatives.

That's a significant obstacle for utility-scale solar thermal companies, which need all the financial help they can get in order to compete with increasingly cheap photovoltaic panels.

If Congress doesn't act, the tax credit will decline to 10 percent on January 1 2017 for utility-scale solar projects, and to zero percent for rooftop solar systems. Though prospective owners of those rooftop solar systems may wince, the demise of the tax credit is less likely to hurt rooftop solar as an industry that it is utility-scale solar. That's because bigger plants have to be competitive with the wholesale price of energy getting sold into the grid, while rooftop systems need only compete with the significantly higher retail cost of that energy as reflected in your electric bill.
