It is totally impossible to have renewable energy only, the costs, the inefficiency, the enormous area of land required, the fact that they don't supply on demand, all mean that the best they can do is reduce by a small amount the amount of fossil fuels required.

By saying that the effect on climate is minimal.

Nuclear power is the only way forward, because eventually fossil fuels will run out, we can build reactors for submarines, ships and even satellites, why cant we build small safe reactors for electricity supply, because governments were interested in atomic bombs and not electricity supply that's why research and development was held up.

Renewable energy is great for long term but will not stop global warming. We should each focus on how we can contribute to a cleaner environment and ignore the idiots trying to control every aspect of life for their own gain.

Renewable energy in combination with nuclear power is the only way to stop global warming.

There isn't any. The relationship between global warming and co2 requires the action of an amplification mechanism, postulated to operate through water vapor. This amplification has never been validated. It is conjecture, not science.
