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.
In one form or another, solar power has been around for thousands of years. As a renewable source of free, green energy, technology has found a way of harnessing the sunâs energy via solar panels which are used either to generate electricity (solar photovoltaics) or to produce heat to warm water (solar thermal).
