Frontotemporal dementia (FTD) or frontotemporal degenerations refers to a group of disorders caused by progressive nerve cell loss in the brain's frontal lobes (the areas behind your forehead) or its temporal lobes (the regions behind your ears).
Solar thermal (heat) energy is a carbon-free, renewable alternative to the power we generate with fossil fuels like coal and gas. This isn't a thing of the future, either.
Geothermal energy is renewable, clean power derived from the thermal energy in subterranean earth. The earthâs thermal energy is created by the decay of radioactive elements in the earth along with the heat from the sun and that remaining from the earthâs creation.Unlike solar power or wind power, geothermal energy is not interrupted by lull times. The technology also has a small carbon footprint in development.he earthâs thermal energy is created by the decay of radioactive elements in the earth along with the heat from the sun and that remaining from the earthâs creation.
