Retail prices for electricity vary widely in the US, from about 8 cents per kilowatt hour in Washington and West Virginia to 19 cents in California. But you wouldn’t know even from the 8 cent price that there is an ongoing revolution in what it costs utilities to generate all that power.
A new generation of combined cycle, gas fired power plants now produce electricity for well under 2 cents per kilowatt hour, while the utilities’ cost to build the power plants has fallen to well under $1000 per kilowatt hour (KwH). While these facilities emit much less CO2 than coal fired power plants, greens concerned about climate change still don’t like the combined cycle gas fired variety because they put out any CO2. You can’t please some people.
Now, a new technology is emerging which will be competitive with the combined cycle versions on cost to build and cost to produce electricity, and the newer plants will emit ZERO CO2! Actually, since part of their process will remove some CO2 from the atmosphere, you could call these negative emission power plants.
