Final answer:
The world utilizes sources like geothermal energy, biomass, coal, and hydroelectric power to produce heat and electricity. Geothermal and biomass are renewable energy sources, whereas coal is non-renewable. Hydroelectric power generates electricity that can be used for heating.
Step-by-step explanation:
The world makes and uses energy for heat through various sources and methods. One major source of heat energy is geothermal energy, which harnesses the natural heat from the Earth's core by converting steam produced by geothermal processes into electricity. This steam can power turbines and is effectively utilized in regions near tectonic plate boundaries.
Biomass refers to the organic material from plants and animals. Biomass can be converted into biofuels like ethanol and biodiesel, or it can be burned directly for heat. It is considered a renewable source of energy because it can be replenished more quickly than it is consumed. Another method of generating heat is by using coal, which, when burned, releases energy but also emits CO2, contributing to carbon emissions.
Hydroelectric power relies on the movement of water, typically flowing down from a high point, to turn turbines that generate electricity. While it doesn't generate heat directly, the electricity produced can be used for heating purposes.
