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.
The U.S. Energy Information Agency projects that solar power will be the fastest-growing source of renewable energy in the United States with annual growth averaging 7.5 percent in the period from 2012 to 2040. In 2013, solar generation accounted for 1.8 percent of total renewable generation.
