Marian L. Tupy a policy analyst at the Cato Institute’s Center for Global Liberty and Prosperity and editor of www.humanprogress.org recently had this interesting post at the CATO Institute and it's worth a read.
Here's a couple points he raised based on a report entitled Germany’s Energiewende: a disaster in the making:
"...the German government now plans to get rid of all fossil fuels, thus increasing the share of renewable energy to 95 percent of total energy supply by 2050."
"...the government has introduced a “renewable” levy on power bills, thus doubling the price of electricity."
"...wind parks and other renewables sometimes oversupply energy so much that they have to be temporarily taken off the grid. Yet the producers still get paid under German law—even if they produce no energy whatsoever. The cost of this particular scheme amounts to €1 billion per year."
