Solar Power currently offers the most promise for the future. It has none of the downsides of the alternatives. Its quiet, non-polluting and non poisonous to humans and to nature.
There are downsides that have been a concern:
- The rare earth elements needed for the panels aren’t in abundant supply, and have been mined in a reckless way in some countries.
- Sunlight is intermittent, meaning that it doesn’t shine at night, and offers a lot less power on dark cloudy days.
- Unless it’s used right away, solar energy has been hard to store as battery technology has lagged the photovoltaic side of things.
- It’s been hard to match up with an old fashioned power grid, so that feed in tarifs have been hard to organise.
- Solar panels have been very expensive, and have relied on government subsidy to get traction and adoption.
The good news is that prices have come right down in the past 10 years, especially in the past 5 or so. New battery technological advancements are being created all the time.
The future for solar energy is very optimistic and exciting. It can offer clean and safe power to the biggest companies, down to the smallest remote communities.
