Wind, water and solar energy is cheap, effective and green. We don’t need experimental or risky energy sources to save our planet

The world is experiencing unprecedented fuel price increases, energy blackmail between countries, up to 7 million air pollution deaths per year worldwide and one climate-related disaster after another. Critics contend that a switch to renewable energy to solve these problems will create unstable electricity grids and drive prices up further. However, a new study from my research group at Stanford University concludes that these problems can be solved in each of the 145 countries we examined — without blackouts and at low cost using almost all existing technologies.
