The big question with regard to solar energy is whether it can reliably replace fossil fuels as a major power source in the future, and this question is not easy to answer. Of the many criticisms that can be raised, two major issues are often levied against solar energy: the first is intermittency – the fact that the available sunlight at a given moment is insufficient to generate power; and the second is cost – the price of producing or installing the solar cells can counteract the money saved on using them in the first place. These new developments don’t necessarily solve all of the problems that can be associated with solar energy, they are addressing the larger, more frequent criticism of it; and, in so doing, they are helping to establish that solar energy isn’t a niche thing but a practical and desirable alternative to fossil-fuel energy.

The school where my kids go encouraged all students to walk to school today. We usually drive them to school, so we had to get them up and out of the house a little earlier this morning. I got up and went downstairs to see if they had already gotten up and saw that all of the lights in the kitchen were on and all of the lights in the den were on and all of the lights in the TV room were on—and no sign of my kids who were still upstairs watching Mythbusters on a laptop. Now you have to realize that my kids are generally very environmentally conscious and very supportive of SolarTown’s mission to promote solar energy. But there sometimes is this huge gap between your views and beliefs and taking action on your beliefs. My son is a hard core believer but a less than hard core doer. And that is the challenge we have on Earth Day: how do we move from what we believe to taking actions, even modest ones like turning off the lights when we are out of the room
