It is way past time for the World Bank Group to change course and invest in clean energy instead of fossil fuels. There are clean energy alternatives literally popping up all over the place.

The two Asian powerhouses have now begun to argue over a shared threat that actually does have impacts on the health and future of their respective populations -- air pollution

While wind energy can seem like a near-ideal solution to our environmental and energy issues, it has not been without its challenges in the United States. But with sufficient R&D into offshore wind farms, the U.S. energy market could open a new chapter for the wind industry.

Without climate change, Obama is open to charges of using taxpayer money to play with the sun and wind and counting on imaginary jobs to save the unemployed. A delusional demi-God claiming he'll change the world.

This massive wind farm is just one of dozens of clean energy projects that have gone onto the grid in 2012, which is shaping up to be a record year for clean energy, as coal use has dropped to record lows.

You wouldn't mount your solar panels in the shade, would you? That would be dumb. Don't do the same with a wind turbine. Remember, both solar and wind are all about the size of the collector and the intensity of the resource.

As the founder and CEO of Bloomberg New Energy Finance, Michael and his team are the world's most comprehensive providers of independent analysis, data and news in the clean energy and carbon markets.

Big, centrist, statesmanlike leadership isn't found in last century's energy sources. We aren't going to frack our way to a cleaner, brighter future. We need a bold, 21st century vision for energy.

While Congress drags its heels, the military is already working to reduce its energy impact and increase the portion of its energy that comes from renewable sources.

There were several developments this week on the climate front that left me deeply disheartened and angry.

What are the top environmental and development issues that will shape 2012? While we can't predict the future, here's a rundown of the key issues to keep an eye on.

When the State Department moved Thursday to postpone a decision on whether the Keystone XL oil pipeline serves the national interests of the United States environmental groups found much to celebrate. But they also surely know that the dispute over Keystone XL -- a proxy, really, for broader and still unresolved debates over oil, climate change and energy policy in America -- is far from over, not least because the delay was much more about political expediency than it was about environmental due process. In reality, the administration's punt highlights just how far environmentalists still have to go to get the country focused on clean energy policies.

When assessing green energy subsidies, a little history helps.
