The greenhouse effect is a natural process that warms the Earth’s surface. When sunlight hits the Earth’s atmosphere, some of the energy is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the Earth’s atmosphere and surface. The greenhouse effect is essential to life on Earth. … Read more

Here is a list of subtopics on renewable energy: Solar energy is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). Wind energy is the use of wind to generate electricity. Wind turbines convert the kinetic energy in the wind into mechanical power, which is then … Read more
What is a pumped storage hydro power plant? A pumped storage hydro power plant is a type of hydroelectric power plant that uses two reservoirs at different elevations to store water. During periods of low demand for electricity, water is pumped from the lower reservoir to the upper reservoir. When electricity demand is high, the … Read more
Hydro Power Hydropower is a form of energy that harnesses the power of moving water. It is a renewable energy source that can be used to generate electricity, provide water for irrigation and drinking, and control flooding. How does hydropower work? Hydropower works by using the force of moving water to turn a turbine. The … Read more
What is Renewable Energy? Renewable energy is energy that comes from natural sources or processes that are constantly replenished. These include sunlight, wind, rain, tides, waves, and geothermal heat. Renewable energy does not produce greenhouse gases or other pollutants, and it is becoming increasingly affordable as technology improves. Why is Renewable Energy Important? Renewable energy … Read more
