There are always controversies persisting, regarding promotion of wind and solar energies as there is a question popping out -what happens when the wind stops blowing or sun stops shining? As an answer to this query, northern Europe plans for a huge electricity grid offered to unite variety of renewable energy sources. They have infact taken a step onward in January after the approval to nine countries that are intending to work together on the project.

The ‘supergrid’ with the help of thousands of miles of high-tech undersea cables will create a bond between farms on blustery British coasts and Belgian tidal power, which is the huge hydroelectric probable of Norway fjords and Germany's gigantic solar collections.

The Department for Energy and Climate Change stated that the scheme for renewable heat would initiate in April 2011.The entire program, which is proposed by Secretary of State for Energy and Climate Change Ed Miliband Britons would be restricted at two percent of renewable energy supply.

Installation of low carbon electricity technologies like solar photovoltaic (pv) panels and wind turbines done by the householders and group of people, will be paid for the electricity they engender no matter if they even use for themselves. They will also get further payment for the electricity they supply into the grid.

President Barack Obama, today proclaimed plans to lessen greenhouse gas emissions of federal government by 28 percent by 2020. This shift would lead to hoard up 205 million barrels of oil. The emission plan is the result of the commitment done by the administration to the Copenhagen treaty to lower GHG emissions of US by 17 percent by 2020.

Barrack Obama stated “As the largest energy consumer in the United States, we have a responsibility to American citizens to reduce our energy use and become more efficient,” He also said, “Our goal is to lower costs, reduce pollution, and shift federal energy expenses away from oil and toward local, clean energy.”
