Renewables became Germany’s most important power source for the first time this year, according to Agora Energiewende.
Over 95 percent of climate scientists have concluded that CO2 is the primary cause of global warming. Solving the problem requires a dramatic reduction in CO2 emissions. Some people are altruistic, but almost all businesses are bottom line oriented and will not reduce their CO2 emissions unless they have an economic incentive to do so. There are two realistic incentives: taxing CO2 emissions or setting up a cap and trade program for CO2. Since increasing taxes is politically unfeasible, the most practical approach is with a cap and trade program.
As a businessman exploring investments, I need simple answers, however complicated the problem. I wish to know: Are microgrids economical? How much investment is needed and for what? What are the factors that principally affect profitability, within the system and in the environment? If microgrids are not profitable at the present, when will they be? I recognize that understanding microgrids as a system requires complicated mathematics and modeling. I’m sympathetic to and respect those who do that.
Recent findings from The Solar Foundation (TSF) show an encouraging surge in the number of K-12 schools installing solar power to save money, reduce carbon emissions, and introduce a new generation of children to the very practical benefits of renewable energy.
For years the geothermal industry has relentlessly boasted that it is a baseload resource, meaning it provides stable power similar to a coal or natural gas plant, except without all of those pesky carbon emissions. While upfront costs to develop a plant are higher than other renewable sources, geothermal leaders say that this baseload aspect makes it a more attractive resource in the long run since the grid needs more stable power as increasing amounts of intermittent renewables enter the landscape.
