The equipment that is required to be off the grid, is made from materials that are fossil fuels and are not easily degradable. Where I live we use electricity from nuclear reactor, but most of US territory gets electricity from burning coal. So basically you buy an electric car to have it fueled by burning coal.

Nuclear plants have high start up cost but low maintenance.

I like wind mills over solar panels.

We seem to be near ending up in a loop, a chain-effect, as cannot be stopped, when it gets warmer and more emissions gets up so it will be warmer and so on.

For our children, time to tell Donald Trump, or he knows and will tell soon?
It is too late. My Snowball effect is already taking place that i have talked about for years. Within 30 years there will be no more winters in my part of FL as the planet will see rapid warming. Just the last 10 years alone should tell anyone it is too late.

I plan on being alive in 30 years so i will see if you are right.

That's good news for Alaska. Maybe 30 years from now we can have a beach-front in Anchorage where thousands of students can come for spring break

Trying to meet this demand with solar and wind by itself is going to make your capacity and storage requirements spiral out of control. Suppose you have requirement to power one 20 watt light bulb, you buy a solar panel that has enough capacity to do this. During an ideal day you can power it for about 8 hours, what about the other 16 hours? Now you need 3 panels and enough storage for two of them. Next day is cloudy? Now you need 6 panels and storage for 5 of them. You can see where this is going, yes?

This would require massive deployment of new infrastructure AND the further you send electric the more that is lost in transmission. Even if such an area could provide somewhat reliable power generation how much do you want to bet on that? This isn't some kind of game where you can say "oops!" if it cannot meet demand.

If you are going to advocate for taking fossil fuels out of the mix what I would suggest is advocating for things that can reliably provide base power. Nuclear, hydro or even the possibility of geothermal.
True.

You should have been invited to attend this TED talk:
https://www.ted.com/talks/debate_doe...nuclear_energy

Wind and solar advocates often "hand wave" away the serious intermittency problem. Until there's an economical way to store massive amounts of electricity for windless and sunless periods, wind and solar will not be able to make up the backbone of the electricity generation system: http://physics.ucsd.edu/do-the-math/...sized-battery/

Germany tried a massive deployment of wind and solar, and it didn't free them from reliance on fossil fuel power plants or significantly reduce their CO2 emissions:

So you argue we only have 10 years left? Then why even worry about climate change just enjoy life till then?

Stop... you are making sense again and destroying others fantasies.
