Coal verses Green Solar
When we burn coal, gas or oil, we are simply harnessing an archived version of that same energy from the sun, stored in plant and animal life, compacted and preserved under the earth’s crust. As Kennedy puts it in his passionate but rational way: “Think about it this way. We’re killing people in foreign lands in order to extract 200-million-year-old sunlight. Then we burn it . . . in order to boil water to create steam to drive a turbine to generate electricity. We frack our own backyards and pollute our rivers, or we blow up our mountaintops just miles from our nation’s capital for an hour of electricity, when we could just take what’s falling free from the sky.”
Falling Costs…
- The average cost of a completed PV system dropped by 16 percent over the past year to $3.00/W.
- The average price of a solar panel has declined by 60 percent since the beginning of 2011.
