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 radiation contains energy that can be transformed into heat (caloric energy) or into electric energy. Primary solar energy is a renewable resource. Wind power can be transformed into electric energy with the use of wind turbines.
