Green Energy Decimates Land Mass Enviroment

Hello green energy - why is it that the environmentalists don't have too much to say about the huge land mass that is required for solar and wind energy, but demand that oil drilling that requires little or no land mass has to be stopped to save a lizard habitat in Texas and Nevada?

Yeah, I know, it all about feeling good about ones self and saving the planet. That we freeze in the winter or roast in the summer, that our economy tanks and millions are unemployed, has little or no impact on the eco fascists. They are well funded by tax dollars and living in luxury, so they see no harm in demanded we change our way of living to suit their fantasy of the 'new America', an America like it was in 1850. Hey, wants the problem with that?


Renewable Energy Sources Require Vast Amounts of Natural Resources

In April, California Gov. Jerry Brown signed into law an ambitious mandate that requires the state to obtain one-third of its electricity from renewable energy sources by 2020. Twenty-nine states and the District of Columbia now have renewable electricity mandates, and there is also support at the federal level, says Robert Bryce, a senior fellow at the Manhattan Institute.
But while energy sources like sunlight and wind are free and naturally replenished, converting them into large quantities of electricity requires vast amounts of natural resources -- most notably, land. Consider California's new mandate.

The state's peak electricity demand is about 52,000 megawatts. Meeting the one-third target will require (if you oversimplify a bit) about 17,000 megawatts of renewable energy capacity.
Let's assume that California will get half of that capacity from solar and half from wind. Most of its large-scale solar electricity production will presumably come from projects like the $2 billion Ivanpah solar plant, which is now under construction in the Mojave Desert in southern California. When completed, Ivanpah, which aims to provide 370 megawatts of solar generation capacity, will cover 3,600 acres -- about five and a half square miles.

The math is simple: to have 8,500 megawatts of solar capacity, California would need at least 23 projects the size of Ivanpah, covering about 129 square miles, an area more than five times as large as Manhattan.

While there's plenty of land, projects as big as Ivanpah raise environmental concerns.
In April, the federal Bureau of Land Management ordered a halt to construction on part of the facility out of concern for the desert tortoise, which is protected under the Endangered Species Act.

Wind energy projects require even more land -- the Roscoe wind farm in Texas, which has a capacity of 781.5 megawatts, covers about 154 square miles.
In the rush to do something -- anything -- to deal with the problem of greenhouse gas emissions, environmental groups and policymakers have determined that renewable energy is the answer. But all energy and power systems exact a toll, says Bryce.
