The Guardian – John Abraham: “In order to combat climate change, we need to rapidly move from fossil fuel energy to clean, renewable energy. The two energy sources I am most interested in are wind and solar power; however, there are other sources that have great potential. Some people doubt how much wind and solar can supply to a country’s electricity grid. This is a particularly challenging question to answer in part because both solar power and wind power fluctuate in both space and time. We all know solar panels work well during the day, when the sun shines – they don’t work so well at night. And wind turbines only send electrons when the wind is blowing.  Fortunately, these two sources of energy fluctuate in ways that complement each other. For instance, solar power generation is highest in the summer and lowest in the winter. Wind power is greatest in the spring and fall. Wind turbines work at night when solar panels are dormant. So, can these complementing variations help balance out the power that the two technologies can provide?  This question was addressed in a very recent paper published in the journal Energy and Environmental Science. The author list included Dr. Ken Caldeira, who is extremely well known for his years of work in environmental science and energy…”
