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 the cleanest and most inexhaustible form of all known energy sources. Solar radiation (heat, light and other radiation emitted from the sun) is the primary energy source for almost all natural processes on earth. The sun provides massive amounts of renewable energy that can be harnessed to provide us with heat and electricity, the two key requirements for running the modern world. The amount of solar energy that falls on the Earth in just one hour is enough to power the world for a whole year. Climate Change. Fossil fuels such as gasoline/petrol, diesel, LPG, coal and natural gas power much of the modern world.
