The world must speed up the deployment of solar power as it has the potential to meet all the world's energy needs, the chairman of an industry gathering which wrapped up Friday in Spain said. "The solar energy resource is enormous, and distributed all over the world, in all countries and also oceans," said Daniel Lincot, the chairman of the five-day European Photovoltaic Solar Energy conference held in Valencia.

Offshore areas along the U.S. coastline hold great potential for wind energy development as the resources are located near the nation's highest areas of electricity demand - coastal metropolitan centers, U.S. Secretary of the Interior Ken Salazar said last week. "Yes, we can build a clean energy future, but it will require American energy, American ingenuity and American courage to tackle our dependence on foreign oil and the growing perils of climate change." -- U.S. Secretary of the Interior Ken Salazar "More than three-fourths of the nation's electricity demand comes from coastal states and the wind potential off the coasts of the lower 48 states actually exceeds our entire U.S. electricity demand," Salazar told a summit meeting of 25X'25 America's Energy Future, a group working to lower America's carbon emissions.

After slow start, wave energy approaches commercial scales The burgeoning wave energy sector, which has endured ups and downs in recent years through initial testing of devices and uncertain government support, has recently set sail with new projects that have brought the industry to the brink of commercial development (Listen to podcast: Emergence of the wave energy industry).

How much energy could be generated by states tapping into internal renewable resources? To date, no study has addressed this question comprehensively. This report is a first attempt to do so. The data in this report, while preliminary, suggest that at least half of the fifty states could meet all their internal energy needs from renewable energy generated inside their borders, and the vast majority could meet a significant percentage. And these estimates may well be conservative.

The nature has paid the price for extraordinary expansion of human civilization; the non-renewable energy resources of the world have been nearly exhausted. Now scientists all over the world are trying to work out a solution to make up the energy shortage that the human civilization is going to face in the coming years. Among many other products under development, the scientists have invested great hopes in the potentials of wind powered electricity generators. This is a system that harnesses the power of the wind to produce usable energy.

The Next100 blog has a post on expanding wind power in California and how advances in mapping wind resources are helping the industry grow - Let It Blow. Solar power is, if you'll pardon the pun, easily the hottest sector of the electric generation market today in terms of public interest. But if California is going to achieve the widely proposed goal of acquring a third of its electrical energy from renewable sources by 2020, wind energy will almost certainly be the flagship carrier of the renewable power industry. Forecasts indicate that achieving the 33% renewable goal would require ramping up wind energy from 2,100 megawatts in 2006 to at least 12,500 MW by 2020. Solar, by contrast, would likely grow from 330 MW in 2006 to 6,000 MW in 2020.

"With heightened concerns about global warming and our country's dependence on foreign oil, the need to accelerate the integration of clean, reliable, domestic energy sources into our country's energy portfolio is clear. Thus we must do more to unlock the potential of our country's location-constrained renewable energy resources. This order is one of the most significant steps this Commission has taken toward that goal.

California's utilities are in a tight spot. They're mandated to procure 20 percent of their electricity from renewable resources by the end of next year. Currently, renewable energy provides only 12 percent of the state's needs. Green energy is needed, and fast. Where to get it? The southeastern corner of California is becoming the state's Wild West of renewable energy. Five years from now this patch of desert will hold one of the largest solar thermal plants in the world. An area of 10 square miles will be filled with 38,000 "sun catchers," which look like enormous satellite dishes with mirrors.

SHANGHAI is rich in clean green wind power and the city is constructing more and more windmills as part of a sustainable energy plan. Zhang Qian flips the switch. The sails of hundred-meter-high windmills rotate in the wind in the mudflats of suburban Shanghai. Row upon row of turbines with huge vanes are generating new clean electricity. Shanghai is rich in sustainable wind resources and is increasing its wind energy capacity as part of an overall plan to reduce pollution and develop clean energy.

This is a new overview of all fossile fuel and renewable energy resources in the U.S. It includes wind and solar resources.

The U.S. Department of the Interior (DOI) last week announced plans to allow geothermal drilling in more than 190 million acres of federal land, spanning 12 Western states. Dirk Kempthorne, secretary of the interior, said that the proposed initiative could increase geothermal power production in the U.S. tenfold. "Geothermal energy will play a key role in powering America's energy future, and 90 percent of our nation's geothermal resources are found on Federal lands," Kempthorne said. "Facilitating their leasing and development under environmentally sound regulations is crucial to supplying the secure, clean energy American homes and businesses need."

The Federal Government will provide $50 million to the geothermal industry to help it begin making the technology viable for baseload energy production. Speaking to Alexandra Kirk on ABC Radio's AM program, the Minister for Resources and Energy, Martin Ferguson, said there was huge potential for geothermal energy in Australia.

As traditional energy sources become increasingly rare and expensive, many homeowners are turning to the skies and learning how to harness energy from the sun. Solar cell technology has been around since the 1950s, but technology has improved considerably and at current levels of efficiency it is worth taking the time and effort to consider a Solar Power Home Now Solar cells are also called photovoltaics, or PV, by the boffins. In basic terms, they are made of semi conducing materials, which, when exposed to the sun go through a distinct process. The solar energy separates the electrons from the atoms within the material and the movement of the electrons creates power, or electricity. Thus light (photons) is converted into electricity (voltage).

# Responsible people see the very urgent need to do something to help our Global environment recover from our excesses. # Do we want our children to be able to breathe clean air and be able to enjoy Nature at its finest? # How can we immediately affect the Environment in a good way and in the shortest possible time? # Most experts agree that the destruction of fossil fuels [ coal, oil, gas etc ] creates massive amounts of harmful materials and that Alternative Energy sources must be found. They suggest alternatives to destroying the Planets Fossil Fuels would be one of the biggest steps we could take on the path back to a cleaner and healthier Planet. # Recent research has forced huge strides forward in Alternative Energy sources such as Wind and Solar Power technology, and in particular making that technology available to the average person for home use. After the initial costs of installation, annual bills could fall to less than 10% of a normal fuel bill!

There are many energy conservation tips taken to have the green power in your surrounding region. Also the charges for the fossil fuels are increasing a lot and creates harm for the environment too.

In South Korea, wind power would be a likely resource to help the world's tenth largest energy consumer meet government goals to lower fossil fuel dependency through greater investment in renewable energy.

We comprehend that the strength of a magnet is fabulously powerful. We are capable to really thoroughly and closely question or examine this attraction and resistance by bringing more than one magnets together.

Renewable Energy World has an article on some large scale efforts to map geothermal power resources in the western US - Western U.S. Entities Move Quickly on Geothermal Mapping. Several large geothermal resource mapping projects are heading toward conclusion so that finally, the power source can be more accurately considered in siting new electricity transmission lines for renewable power development. Given the Obama administration's investment focus on new transmission line development, the result of the mapping efforts should be a relatively rapid increase in the number and size of commercial-scale geothermal projects.

"Research Report on China's Natural Gas Industry Chain, 2013-2017" Natural gas is a kind of energy that is quite clean and environment friendly. Coal is the major primary energy consumed in China, so the increasing consumption of natural gas is helpful to optimize the energy structure.
