This is in response to the article “Report: Mass. has ample solar power potential” [Gazette, July 10].

For starters, where does this power come from at night or during a major rainstorm? At least the article acknowledges that wind and hydro energy would also be used but the overall thrust of the article, based on the numbers given, implies that solar alone would do the job. Too many people I have asked reply that we at night get power from wind. But what about during a calm night, when neither power is available?

One issue identified is the use of ground-mounted solar panels. The debate/conflict is between those advocating for such solar farms because of the power they could generate and conservationists who are opposed, especially if it involves cutting down trees. Using roof-mounted and canopy panels, when fully exploited, could provide a huge amount of power, but not enough to satisfy all our needs, even when supplemented by wind.

The question not addressed is what percentage of our total power should come from solar. If it is to be the primary source, then solar farms would be required, but how much is really needed? If wind is enough to cover the loss of solar power at night or during that rainstorm, why do we need solar at all? Just use wind power alone. But then what do we do on that calm night?

A big problem with solar is providing power when the sun is not shining. Much of the power they produce would have to be stored in batteries. Another thing that the average person does not realize is the horrendous environmental cost of creating batteries and then disposing of them at the end of their lives.

Another clean source of power that is rarely mentioned is the new small modular nuclear reactors. These do not have the problems inherent in current nuclear reactors that came out so long ago. They can be assembled in factories and shipped to their ultimate location. They don’t require a water source for cooling and their waste is easily handled.
