Exploring Energy Resources

What are the main types of renewable energy sources?

• Coal, oil, tidal energy

• Nuclear, fossil fuels, natural gas

• Solar, wind, hydroelectric, geothermal, biomass

• Hydrogen, wave energy, thermal energy

How does solar energy convert into electricity?

• Solar panels reflect sunlight to generate electricity.

• Solar energy is converted into electricity through chemical reactions.

• Solar panels convert sunlight into electricity using the photovoltaic effect.

• Solar panels store electricity for later use.

What is the primary disadvantage of wind energy?

• Intermittency of wind availability

• Excessive noise pollution

• High installation costs

• Limited geographic availability

Name two examples of non-renewable energy sources.

• hydroelectric, geothermal

• solar, wind

• coal, oil

• biomass, tidal

What is the process of converting biomass into energy called?

• Biomass fuel production

• Biomass energy conversion

• Biomass waste management

• Biomass energy extraction

How does geothermal energy work?

• Geothermal energy relies on solar power for heating.

• Geothermal energy is produced by burning fossil fuels.

• Geothermal energy is generated from wind currents.

• Geothermal energy harnesses heat from the Earth's interior for electricity generation and heating.

What are the environmental impacts of fossil fuels?

• Fossil fuels have no impact on climate change.

• Fossil fuels are a renewable energy source.

• Fossil fuels have significant environmental impacts including air pollution, water contamination, habitat destruction, and contribution to climate change.

• Fossil fuels improve air quality and promote biodiversity.

Explain the principle of nuclear fission.

• Nuclear fission is the splitting of a heavy atomic nucleus into smaller nuclei, releasing energy and neutrons.

• Nuclear fission is the process of converting matter into energy without any nuclear reactions.

• Nuclear fission involves the absorption of energy by an atomic nucleus.

• Nuclear fission is the fusion of light atomic nuclei into heavier nuclei.

What is energy efficiency and why is it important?

• Energy efficiency increases energy consumption and raises utility bills.

• Energy efficiency is only relevant for industrial sectors, not households.

• Energy efficiency is important because it reduces energy consumption, lowers utility bills, decreases greenhouse gas emissions, and conserves natural resources, contributing to a more sustainable environment.

• Energy efficiency has no impact on environmental sustainability.

How can energy efficiency be improved in homes?

• Use incandescent bulbs for lighting

• Upgrade insulation and appliances, seal leaks, use programmable thermostats, and consider renewable energy.

• Keep doors and windows open for ventilation

• Install larger windows for better sunlight
