Look, nothing is explosive or as cheap as oil. I'm not going to deny that. But we still have the capacity to replace what we have with a green grid, it is just it isn't done because of ideological barriers and lobbying. How can you say we can't do green energy if we haven't tried a complete revamp of our energy sector?
As I said in an earlier post, there is The Space Based Solar Network, or SBSN. I really don't want to type everything out because I have before. Basically this method only uses the sun, and can power the world three times over while cutting your electricity bill in half. We have the money to do it, trust me. 10 billion dollars over 10 years. 100 billion. If that is too low for you to believe me, because a lot of people don't when I say that, then multiply it by 10. 100 billion dollars for 10 years or 1 trillion dollars. 100 billion can easily be printed.
The only reason why we don't have green energy is because of the lobby and the jobs lost. Otherwise we could turn completely green. Homes could power themselves, taking the load off of the SBSN. We would probably do that through tax incentives, and when the technology gets cheaper for the typical family. And well, they would get paid instead of paying for electricity. There are already ideas for power storage for the home family. Fuel cells were the ones I read about, I bet there are other ideas. There are storage technologies designed for power stations. We have the design, there is enough power from the sun, we have the technology, but we don't do it because of ideological barriers and lobbying.
By the way, all methods could be used in accordance with the SBSN. Solar, wind, tidal, geothermal, I mean you name it. But that would probably all be more expensive than just sending three satellites in space to collect solar energy and beam it down to Earth.
