More and more people are recognizing the environmental and economic benefits of renewable energy. Solar energy, the cleanest and most abundant renewable energy source available. Solar thermal energy can be applied with fossil fuels or independently in order to reduce the cost of generated electricity and CO2 emission.

Research shows that using solar energy in addition to fossil fuels results in both lower carbon dioxide emission and lower cost of the generated electricity. Moreover, analyses of the cycles revealed that heat recovery leads to higher efficiency while increasing capital costs.
