“One of the greatest promises of the high-tech future, whether made explicitly or implicitly through shiny clean concept sketches, is that we will have efficient energy that doesn’t churn pollutants into the air and onto the streets.
But here in the present, politicians and even many clean energy advocates maintain that a world run on hydrogen and wind, water and solar power is not yet possible due to technical challenges like energy storage and cost.
Yet Stanford University researchers led by civil engineer Mark Jacobson have developed detailed plans for each state in the union that to move to 100 percent wind, water and solar power by 2050 using only technology that’s already available. The plan, presented recently at the AAAS conference in Chicago, also forms the basis for The Solutions Project nonprofit.
Clean energy would save an average American consumer $3,400 per year than the current fossil fuel regime by 2050, the study lays out. That’s because the price of fossil fuel rises regularly, but with clean energy — where raw materials are free — once the infrastructure is built, prices would fall.
For example, in California, the researchers found that it’s already possible to use wind, water and solar energy to meet demand 99.8 percent of the time.
“The conclusion is that it’s technically and economically feasible,” Jacobson told Singularity Hub.”
