@Baldimo,
we live in eastern ontario and most of our eletrical energy comes from the eastern canadian and U.S. grid . we have one power staion within about 20 miles of our city and it can use either oil or gas - usually they buy what's least expensive .
during the last several months construction of large scale windfarm has been started off-shore lake ontario , a large solar collection system is being built adjacent to the power station and they have also started growing renewable energy crops that will be used for producing electrical energy starting next year .
i could even see lake ontario water flow being utilized to produce power some day .
being a layperson , it seems to me that combining ALL available sources of producing energy is not a bad way to go . in addition , much energy can be saved by industry and individuals through clever use of proper heating , air-conditioning , lighting , insulation ... ...
perhaps the eventual bill for electriccity will be higher than now , but to me it's the availability of electricity that's most important .
if energy use had not been modified over time , we would still be using horse and buggy , and steam engines , if we are lucky .
there is always great reluctance to accept something new (the expression : "we don't need any new-fangled ideas" has always had and will continue to have many adherents ) .
when the first space rocket went up (remember : SPUTNIK ) , there was great exitement . it's now become almost a ho-hum experience .
i don't think many questions have been asked about the cost - cost recovery -
usefulness ... ... of sending space ships up - it's just being done .
imo the same thing will eventually happen to new power sources - perhaps better methods will be found and implemented - but in the meantime we'll use what's available .
