Experts estimate that we could supply humanity’s total energy needs for the next 2 million years with only 0.1% of the heat content of the Earth. Geothermal energy uses heat from the earth’s core and produces little to no waste products or carbon dioxide (CO2) emissions. So, we had to ask: What is the history of geothermal energy?
Biogas is a combustible gas derived from biomass sources which some believe to be a more sustainable alternative to natural gas. Turning our waste into energy, instead of letting the gasses they emit enter our atmosphere, can help mitigate climate change. So, we had to ask: What is the history of biogas?
