FAQs
There are five major renewable energy sources:
Solar energy from the sun. Geothermal energy from heat inside the earth. Wind energy. Biomass from plants.
What is the answer to the energy crisis? ›
Energy transition to renewable energy sources
Unlike fossil fuels, some energy sources are totally renewable, and do not emit greenhouse gases. These clean and sustainable alternative energy solutions include solar energy, hydropower, wind energy, geothermal energy and biomass energy.
Could renewable sources of energy produce enough energy to eliminate the need for fossil fuels in the near future? ›
Final answer: In response to the statement 'Renewable sources of energy could produce enough energy to eliminate the need for fossil fuels in the near future', the answer is scientifically and methodologically, yes.
What are the 7 main energy sources? ›
Primary energy sources take many forms, including nuclear energy, fossil energy -- like oil, coal and natural gas -- and renewable sources like wind, solar, geothermal and hydropower.
What is an energy source short answer? ›
Energy sources are forms of potential energy that can be used to perform work. Energy sources are categorized as renewable if they constantly and rapidly renew themselves for steady, reliable use. Any other source of energy is considered nonrenewable.
Can solar power replace oil? ›
So while my solar panels can certainly make a contribution, they can't replace that dirty CO2-producing coal plant that provides my electricity when the sun isn't shining. The only thing that could do that before 2050 is a new nuclear power plant.
Is nuclear energy clean? ›
Nuclear is a zero-emission clean energy source. It generates power through fission, which is the process of splitting uranium atoms to produce energy.
Can electricity replace fossil fuels? ›
Renewables can effectively replace fossil fuels, creating crucial environmental, social and economic benefits. Global dependence on oil, natural gas and coal–and the damage this dependence inflicts–is well documented. But a transition away from fossil fuels is in progress and simply needs to be expedited.
What is the cleanest energy source? ›
Nuclear energy is sometimes referred to as a clean energy technology as it produces nearly zero carbon dioxide or other greenhouse gas emissions. Nuclear energy also avoids producing air pollutants that are often associated with burning fossil fuels for energy.
What are the pros and cons of solar energy? ›

Renewables are set to contribute 80% of new power generation capacity to 2030 under current policy settings, with solar alone accounting for more than half of this expansion.
What is the source of all energy? ›
The energy of the sun is the original source of most of the energy found on earth. We get solar heat energy from the sun, and sunlight can also be used to produce electricity from solar (photovoltaic) cells. The sun heats the earth's surface and the Earth heats the air above it, causing wind.
What is the primary source of energy answer? ›
The primary source of energy on earth is the sun. The energy is produced in the sun's core.
What are the sources of energy pdf? ›
We can broadly categorize these sources as commercial and noncommercial. The commercial sources include the fossil fuels (coal, oil andnatural gas), hydro-electric power and nuclear power, while the noncommercial sources include wood, animal waste and agricultural wastes.
What is a source of energy Grade 7? ›
Grade 7 Science Worksheets
There are two types of energy resources. Non-Renewable resources are coal, oil, wood, or gas. Renewable resources are wind, solar, hydroelectric, and also wave power.
