If it were only the Republicans! The oil industry corrupts politicians of all parties in all countries. The other problem is that oil, gas and coal are extremely cheap: drill the soil, collect the oil, light it and you have heat. Competing against that is extremely difficult. Presently and after big efforts, renewables are cheaper than nuclear electricity, and that's all. Electricity for cars is cheaper than gasoline only because the user pays 20% taxes on it instead of 400%. Governments don't want to abandon these huge incomes.
You may notice that the same propagandists advocate nuclear energy "because zero carbon" as well as oil. This tells that they don't work for oil companies. After a hurricane (Sandy?), Obama closed the CIA's Climate cell (or group, I don't know their English name), and the propaganda activity dropped a lot. The other groups remain.
Individuals can do a lot. Elon Musk lets build electric cars that are desirable, while other companies made only ugly sluggish big toys. His company offers good batteries for home or plant size whose price and endurance are competitive. This does tackle climate change, without the governments, and in many countries against them.
Scientists who improve lithium batteries or develop sodium ones bring much to renewables. Or better, improve the cost and efficiency of power lines as long as a continent
, to harvest wind where available.
Storage is one enabling technology for renewables. Developing underwater bags, underwater concrete vacuum spheres, flywheels, cheaper than batteries, would make a differencehttps://www.scienceforums.net/topic/59338-flywheels-store-electricity-cheap-enough/
storage would let use cheap fossil fuels in some uses, typically electricity plants, not cars. Useful goal, more or less at reach, but it failed recently.
As compared, capturing CO2
from the air is damn difficult. Technically and economically, but not only. Who shall pay for it while it brings no money? Europeans will answer "I don't pay to remove what the Chinese emit".
Whether we'll base the storage and transport of energy on hydrogen some day, I don't know. For helicopters and aeroplanes it looks fantastic, for cars and buildings I'm not surehttp://www.scienceforums.net/topic/75102-electric-helicopter/?do=findComment&comment=745535http://www.scienceforums.net/topic/73798-quick-electric-machines/
Presently I believe fusion reactors of all kinds are a dead end because the regeneration of tritium, if any possible, will be as polluting as uranium fission. But if you find a practical and clean way, I'll happily change my mind.
