I came across this headline at Bloomberg.com written by Tom Randall--
Wind and Solar Are Crushing Fossil Fuels
Record clean energy investment outpaces gas and coal 2 to 1
After reading his article I think I can see why...
Naysayers will point out the weakness in being able to store electric. My response would be. There's a huge amount of overhead (extra generators, wire repair crews and alternative wire routes) required of utility companies to keep the current flowing. Current flows nearly at the speed of light. With any breakdown the results are felt down line in a matter of seconds. Generating stations can't store electricity either. Reliability doesn't come cheap.
In order to ally those arguments requires further explanation. For decades the landline telephones continued to operate reliably however long power was out. If one were to visit the central terminals in those days they'd find dozens of batteries nearly identical to those used in today's electric forklifts. They were capable of storing huge amounts of low voltage current. Since telephones operated on direct current they were a perfect solution. One may continue to argue, but they were DC we need AC. Ever hear of an inverter?
Electrical storage batteries have been improving, but for the average homeowner a fork lift battery would be more then adequate. Someday if a homeowner wants to spend more money on something that does a better job that's also a option.
Point Is...
As always money will be the main factor how quickly things come about. Investors seem to be moving on. With it too the fossil fuel industry and electrical suppliers who have the foresight not to be left behind. According to the New York Times even Saudi Arabia is restructuring it's economy away from supplying fuel oil.
I'm hopeful we are starting to see a snowball effect headed in this direction.
This is a good thing all the way around.
