Much of the energy we use nowadays (as of 2016) is from the so-called non-renewable sources - mainly coal, and petroleum.
For a while, yes. Long term, no. It is a non-renewable resource, and so we have to switch over to alternative energy sources.
Energy can be both a resource and nonrenewable. Renewable energy sources such as sunlight and wind are resources that can be naturally replenished. Nonrenewable energy sources like fossil fuels (coal, oil, natural gas) are finite and formed over millions of years, making them nonrenewable.
Coal is a nonrenewable resource, while pine trees are a renewable resource. As sources of energy, the difference between coal and pine trees is that coal is a nonrenewable resource, while pine trees are a renewable resource.
Nonrenewable
The major nonrenewable and renweable sources of energy include oil and solar sources respectively.
nonrenewable energy sources are sources that are depleted sources as fossil fuels (wood, coal, natural gas, and oil)
Mainly because it isn't an energy resource.
nonrenewable energy
Coal, oil, and natural gas are the main three nonrenewable primary energy sources.
Because renewable sources can be replenished (apex) because we will not run out of them
nonrenewable energy
Geothermal energy is the least used nonrenewable resource to generate electricity. This is because geothermal power plants are location-specific and require specific geological conditions to harness underground heat sources for energy production.
