There are grounds for concern about solar power

The expansion of solar energy production could result in significant environmental damage.

Sunlight is the greatest life-giving force on our planet. It is also a potential source of more clean energy that we can ever use. The amount of solar energy reaching the surface of the Earth is estimated to be a staggering 3.4 million exajoules (EJ) a year. To give you some idea of how much this is, a single EJ is one quintillion (one million trillion) joules (the Tōhoku earthquake and tsunami measured in at 0.175EJ). The sun’s rays bathing the Earth in a single year are enough to supply humanity, at its current rate of primary energy consumption, with energy for 7,000 to 8,000 years.
