Q & A

What is renewable energy?

Renewable energy refers to energy that is produced from natural resources that can be replenished, such as sunlight, wind, and water. These sources of energy do not deplete the Earth's resources and can be continually regenerated.

Why is renewable energy considered environmentally friendly?

Renewable energy is considered environmentally friendly because it produces little to no pollution, unlike non-renewable energy sources that emit harmful pollutants into the atmosphere, contributing to air pollution and climate change.

What are some examples of renewable energy sources mentioned in the script?

Examples of renewable energy sources mentioned include solar energy (sunlight), geothermal energy (heat from the Earth), wind energy, hydropower (water), biomass (organic matter), biogas, and ocean wave energy.

How is water used as a source of renewable energy?

Water is used as a renewable energy source due to its gravitational properties, always flowing from higher to lower elevations. Hydropower plants or water mills harness this flow to generate electricity.

What is solar energy and how is it utilized?

Solar energy is the energy obtained from sunlight. It is harnessed using solar panels, which absorb sunlight and convert it into electrical energy, providing a renewable and sustainable power source.

Can wind energy be used globally? Why or why not?

Yes, wind energy can be used globally because wind is a widespread natural resource. Wind turbines are installed to convert wind movement into mechanical energy, which can then be transformed into electricity.

What is geothermal energy and where is it typically used?

Geothermal energy comes from the heat stored within the Earth's core. It is typically used in regions near active volcanoes, where geothermal power plants are installed to harness this heat for electricity generation.

What is biomass and how is it used as an energy source?

Biomass refers to organic materials derived from living organisms, such as plants and animals. Biomass energy can be generated by using leftover agricultural products, like corn or coffee waste, as fuel for power generation.

How is biogas produced and used for energy?

Biogas is produced from the anaerobic decomposition of organic materials, such as animal manure or plant waste. This gas can then be used to produce heat and electricity, making it a useful renewable energy source.

What is the role of ocean waves in renewable energy production?

Ocean waves can be harnessed to generate energy using turbines placed in areas with strong wave activity. These turbines capture the kinetic energy of the waves and convert it into electricity.
