Energy freedom (100% conversion to alternative) achievable in 20-40 years. Needed: political will


If someone told you there was a way you could save 2.5 million to 3 million lives a year and simultaneously halt global warming, reduce air and water pollution and develop secure, reliable energy sources – nearly all with existing technology and at costs comparable with what we spend on energy today – why wouldn’t you do it?

According to a new study coauthored by Stanford researcher Mark Z. Jacobson, we could accomplish all that by converting the world to clean, renewable energy sources and forgoing fossil fuels.

“Based on our findings, there are no technological or economic barriers to converting the entire world to clean, renewable energy sources,” said Jacobson, a professor of civil and environmental engineering. “It is a question of whether we have the societal and political will.”

He and Mark Delucchi, of the University of California-Davis, have written a two-part paper in Energy Policy in which they assess the costs, technology and material requirements of converting the planet, using a plan they developed.

The world they envision would run largely on electricity. Their plan calls for using wind, water and solar energy to generate power, with wind and solar power contributing 90 percent of the needed energy.

Geothermal and hydroelectric sources would each contribute about 4 percent in their plan (70 percent of the hydroelectric is already in place), with the remaining 2 percent from wave and tidal power.

Vehicles, ships and trains would be powered by electricity and hydrogen fuel cells. Aircraft would run on liquid hydrogen. Homes would be cooled and warmed with electric heaters – no more natural gas or coal – and water would be preheated by the sun.

Commercial processes would be powered by electricity and hydrogen. In all cases, the hydrogen would be produced from electricity. Thus, wind, water and sun would power the world.

  1. Well this is good news. You always hear green alternatives cost more, and green products can’t compete in the market place. I’ve been focusing on disposable and single-use plastic lately ( and it’s been quite amazing how many groceries (not even to speak of inedible products!) I can’ t buy if I refuse plastic packaging. Yesterday I was looking for toothpaste packaged without plastic. Nope. And potato chips. Nada. We have plenty of plastic packaging alternatives, what is our problem? In fact I found a product that had a clear plastic inner bag, which you could see thru a cutout portion of the outer cardboard box, which was made from wood pulp. How do they make wood pulp into a clear film? It’s just crazy. I showed it to a store clerk and he looked at me and said “that’s just amazing”. It looked so much like petroleum plastic you would never know difference. So why are we still wrapping stuff in plastic? It’s a conundrum I cannot answer. Except that I suspect people don’t understand plastic does not biodegrade, and people think plastic can be recycled the same way glass and aluminum can.

  2. plastic CAN be recycled, in aus we make heaps of stuff from it.
    and it can be useed as fuel hi temp incinerators stop outgasses, and oils reclaimed from it and also from old tyres.
    until they find better non toxic ways tro make solar cells, see evergreen took 138 mil us taxpayers money for solar cells and now is offshoring to china..that denmark and china make most wind urbines which use a lot of copper lithium etc? so BTW do electric cars.
    if the cooling continues the last problem we need worry about is carbon(we never did) solar and wind wont get folks through severe cold too well. UK functional under 2% last winter, they imported powewr from France. so did Denmark, the wind wasnt enough there either.

  3. hydrogen in aircraft? you first:-)
