"It no longer makes sense for any country to install a technology that can create a catastrophe such as Chernobyl or Fukushima - especially when far better alternatives are available," he wrote.
In places such as Germany, Spain, Portugal, Australia and parts of the United States and India, residential-scale solar production has already reached "grid parity" with average residential electricity prices, he wrote
"In other words, it costs no more in the long term to install solar panels than to buy electricity from utility companies - without government subsidies," Wadhwa wrote. In the late 2020s, solar energy will cost a fraction of what fossil fuel - and nuclear-based alternatives do,' he predicted suggesting, "This is the reality - believe it or not."
Solar, wind, biomass, thermal, tidal, and waste-breakdown energy, and a host of newer energy technologies, are becoming increasingly practical to install worldwide, Wadhwa noted. Obama, he suggested, "should not be prescribing medicine that he would not take himself. Germany is working towards phasing out all of its nuclear plants by 2022 and many other developed countries are looking to follow its lead, he said. "So why subject India and other developing countries to these dangers?" Wadhwa asked.
Instead of trying to chain India to the past with technologies such as nuclear, Obama should help the country leapfrog into the future with clean energy, he wrote. "This will benefit not only India, but also the world."
