The cost of producing electricity via wind power is expected to fall 24-30 percent by 2030 and 35-41 percent by 2050, according to a survey of the world’s foremost wind power experts.

Renewable Portfolio Standards are Responsible for Much of the Green Growth

Renewable Portfolio Standards are Responsible for Much of the Green Growth

There’s nothing like a government incentive to grow green energy. And that’s why the Lawrence Berkeley National Laboratory is saying that renewable portfolio standards enacted by at least half the states is responsible for 60 percent of non-hydro renewable sources. Those green standards vary by state but generally require utilities … Read more »
