power plants I"m familiar with...funding is approved for three new GEN-IV designs and they should be ready for licensing and construction in 6 - 10 years...meanwhile, Wind and Solar can be added in fairly quickly without their being relied on for "Grid Level" power.
We absolutely NEED to get away from using Fossil Fuels for heat and power (except where absolutely necessary...e.g. air transport....most every country and major energy company understands this and is making long term plans accordingly...there's no way Exxon or Chevron are going to pump billions into their current 'Cash Cow' income sources, so it is incumbent on government and financial institutions to work together to help speed the development of these new energy sources which will likely be privately owned, operated, with some degree of federal and state regulation (e.g. nuclear)
Again, all of this takes time...encourage your Representative/Senators to get on board and make it happen...with as little disruption to the lives of you and me.
