Shifting the world to 100 percent clean, renewable energy as early as 2030 -- here are the numbers  

Posted by Big Gav in

PhysOrg has a post on an article in next month's Scientific American describing how to transition to 100% renewable energy by 2030 - Shifting the world to 100 percent clean, renewable energy as early as 2030 -- here are the numbers.

Mark Jacobson, professor of civil and environmental engineering, has coauthored an article that is the cover story in the November issue of Scientific American. The article presents new research mapping out and evaluating a quantitative plan for powering the entire world on wind, water and solar energy, including an assessment of the materials needed and costs. And it will ultimately be cheaper than sticking with fossil fuel or going nuclear.

To make clear the extent of those hurdles - and how they could be overcome - they have written an article that is the cover story in the November issue of Scientific American. In it, they present new research mapping out and evaluating a quantitative plan for powering the entire world on wind, water and solar energy, including an assessment of the materials needed and costs. And it will ultimately be cheaper than sticking with fossil fuel or going nuclear, they say.

The key is turning to wind, water and solar energy to generate electrical power - making a massive commitment to them - and eliminating combustion as a way to generate power for vehicles as well as for normal electricity use.

I have not had a chance to read this yet, but a few things stick out.

"And it will ultimately be cheaper than sticking with fossil fuel or going nuclear, they say."

This is and has always been true. The lead nuclear expert (at the time) once stated on the discovery network that nuclear would have never have been cost competitive with alternative energy if it had not been heavily subsidized for weapons development.

I think major advances since his time (1950's) have given us many viable fission and fusion options that may become sustainable.

And stating that renewable energy will "ultimately be cheaper than sticking with fossil fuel" is just an inarguable fact.

Time is its only competition.

100% by 2030 is a great goal/dream shared by very few who control, power, energy and policy.

Yet if they do not listen to all the reasonable options we have to shift towards renewable, it will be a VERY unreasonable world by 2020.
