If environmentalists were serious, they would embrace nuclear energy. It has downsides, but it does not contribute to global warming. Environmentalists oppose nuclear energy on political grounds, not scientific ones. Wind and solar energy are becoming more productive and reliable, but they still cannot supply the base load for electrical power. They are too dependent on the vagaries of the weather.
Nuclear power cannot be made 100% safe, no power system can, but it can probably be 99.9% safe, and if well designed the 0.1% failures can be managed without great loss of life, while global warming could destroy a substantial portion of the world’s population through rising sea levels, crop failures, fierce storms and so on.
Part of the new infrastructure plan could finance more research on safer reactor designs, and construction of new reactors because new nuclear power stations are needed sooner, rather than later. New nuclear power reactors will be expensive and take a long time to build, so we need to get started sooner, rather than later.
