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.
Solar energy is a renewable resource whose use does not affect its future supply. Conventional power plants use fossil fuels or nuclear energy as a heat source to boil water. The steam from the boiling water rotates a turbine, which activates a generator to produce electricity.olar energy facilities use concentrating solar power (CSP) as the heat source to boil water, or they convert sunlight directly into electricity using solar cells, also known as photovoltaics (PV).
