Electric heat
I just got done sitting on my bed, with my face over an electric radiator. What a logistical nightmare.
For my face to absorb that heat, electricity was conducted through an inefficient metal. I won't go into where the metal may have come from. The electricity was conducted to my house from a generator on another island many miles away, which was strategically built at the bottom of a pipeline. By connecting the pipeline to a lake thousands of feet above, the lake water's potential energy was converted to the kinetic energy of the water rushing through the pipe. When the pipe's water hit a turbine connected to the generator, the kinetic energy became electrical energy.
The lake wound up thousands of feet above the turbine thanks to radiant energy from the sun. Oceans, and water on land was evaporated thanks to the combustion of a distant cloud of gas we call The Sun. Water vapor was uplifted via thermal convection to create clouds high in the Earth's atmosphere. When condensed, this water vapor then fell back to the surface of the Earth as rain, snow, sleet, hail, pow, mashed potatoes, graupel, and popcorn. This precipitation collected in depressions on the land's surface. Where these depressions were big and bowl-shaped enough, lakes occasionally formed, one of which happened to be conveniently close to my bedroom.
