I think solar power is probably one of the better solutions. It’s already possible to implement for many people’s day-to-day electricity needs and a lot of improvements are being made in durability, size, and battery life. And it’s a lot less intrusive and friendlier to wildlife than most other energy sources.
So we need something safe, predictable, affordable, plentiful and pollution-free but no current energy source can achieve all of these.
Nuclear power and fossil fuels pollute the environment and will run out but wind and solar power is relatively expensive to produce and not predictable because it is intermittent.
There isn’t a single solution — we’ll have to use a mixture of different sources. Unfortunately, at the moment it’s very difficult to see how we can rule out nuclear power — it provides a huge amount of energy; wind, wave, solar etc… currently can’t meet the energy demand alone. The only alternative would be to start rationing the supply…
