Solar Energy vs Fossil Fuels: How Do They Compare?

When we compare the cost of solar energy vs. fossil fuels, we have to factor in the relative subsidies that are keeping costs low. In the case of solar power, the Investment Tax Credit (ITC) currently covers 26 percent of any U.S. solar installation.. While renewable energy skeptics have criticized the ITC for being a costly taxpayer-funded stimulus, the reality is that
