Detailed explanation-1: -Nonrenewable energy resources include coal, natural gas, oil, and nuclear energy. Once these resources are used up, they cannot be replaced, which is a major problem for humanity as we are currently dependent on them to supply most of our energy needs.

Detailed explanation-2: -The reserves of these substances took billions of years to form, and it will take billions of years to replace the supplies used. As such, the supplies of nonrenewable resources are finite and cannot be replaced. Humans extract these resources in gas, liquid, or solid form and then convert them to suit their needs.

Detailed explanation-3: -Renewable energy is energy that comes from a source that won’t run out. They are natural and self-replenishing, and usually have a low-or zero-carbon footprint. Examples of renewable energy sources include wind power, solar power, bioenergy (organic matter burned as a fuel) and hydroelectric, including tidal energy.

Detailed explanation-4: -The short answer: yes. The big question: when? A full transition from fossil fuels to renewable, clean energy will not happen overnight, but the need is growing more urgent.

Detailed explanation-5: -Renewable resources include solar energy, wind, falling water, the heat of the earth (geothermal), plant materials (biomass), waves, ocean currents, temperature differences in the oceans and the energy of the tides.
