solar
What is one way renewable energy helps the environment?
Reduced Greenhouse Gas emissions
Explain two major environmental problems caused by extracting and burning coal.
Air pollution
What does "photovoltaic cells" mean?
Devices that convert solar energy directly into electricity.
Name one way that nuclear energy can harm the enviornment
mining for uranium can lead to health risks and pollution
production of radioactive waste
habitat destruction
What is a major disadvantage of solar energy at night
Lack of sunlight, meaning electricity can not form nor generate
Explain how renewable energy can help a developing country economically and environmentally.
Reduces costly fuel imports and decreases pollution-related health problems
Why does natural gas, despite being "cleaner," still pose environmental risks?
Methane leaks during extraction and it can lead to a powerful greenhouse gas.
Define "energy efficiency."

Formed from the remains of tiny sea plants and animals that died hundreds of millions of years ago
Name two types of biomass energy
Wood, crops, seaweed,or animal waste
Describe two health benefits of switching from coal to renewable energy sources.
Cleaner air reduces respiratory diseases; less water contamination improves public health.
How does mining for coal impact local environments and communities?
Causes habitat destruction, water pollution, and soil erosion
What is the unit "kWh" used to measure?
Energy Consumption
