At present - yes.
The most popular renewable energy sources currently are: Solar energy. Wind energy. Hydro energy. Tidal energy. Geothermal energy. Biomass energy.
Renewable energy sources are naturally replenished and can be sustained indefinitely, whereas non-renewable sources will eventually run out. Examples of renewable energy sources include solar, wind, and hydro power.
Non-renewable energy sources do not include solar energy, wind energy, and geothermal energy. These sources are considered renewable because they can be naturally replenished in a relatively short period of time.
Non-renewable energy sources used in power stations around the world include coal, natural gas, and oil. These sources are finite and produce greenhouse gas emissions when burned for energy generation. The reliance on non-renewable energy sources has led to environmental concerns and efforts to transition to more sustainable, renewable energy options.
Most of Ontario's energy comes from non-renewable sources such as natural gas and nuclear power. While the province has been investing in renewable energy sources like hydroelectric and wind power, the majority of its energy still comes from non-renewable sources.
renewable source of energy can be regenerated but non-renewable source of energy can not be regenerated.
Renewable energy sources are often referred to as alternative energy sources because they provide alternatives to traditional fossil fuels, which are finite and contribute to environmental issues like climate change. These renewable sources—such as solar, wind, hydro, and geothermal energy—are sustainable and can be replenished naturally. As the world seeks to reduce carbon emissions and dependence on non-renewable energy, these alternatives are increasingly recognized as viable solutions for a cleaner energy future.
This is a world-wide problem not confined to any particular country; it exists because the cost of non-renewable energy sources is, so far, significantly less than the cost of renewable sources.
Around 20% of world electricity is from renewable energy in 2009. More than 80% of the renewable energy use is hydroelectric which had a lot of installation limit. Progress on renewable energy is rather slow to the energy crisis.
