English 7 Unit 10 Energy Resources

What are renewable energy resources?

• Renewable energy resources are sources of energy that are only available during certain times of the year.

• Renewable energy resources are sources of energy that deplete over time and cannot be used repeatedly.

• Renewable energy resources are sources of energy that are replenished naturally and can be used repeatedly.

• Renewable energy resources are sources of energy that are harmful to the environment and not sustainable.

Give an example of a non-renewable energy resource.

• Wind energy

• Solar power

• Hydropower

• Fossil fuels

Explain the concept of energy conservation.

• Energy conservation is the process of creating new energy sources.

• Energy conservation involves wasting energy whenever possible.

• Energy conservation only applies to certain types of energy.

• Energy conservation is the principle that energy cannot be created or destroyed, only transformed from one form to another.

How can solar energy be harnessed?

• Storing sunlight in batteries for later use

• Using solar panels to capture sunlight and convert it into electricity

• Using wind turbines to capture sunlight

• Converting sunlight into heat energy directly

What are the advantages of wind energy?

• Advantages of wind energy include being renewable, clean, abundant, reducing greenhouse gas emissions, creating jobs, and being cost-effective.

• Wind energy is harmful to wildlife

• Wind energy is not reliable

• Wind energy is expensive to produce

Describe the process of hydroelectric power generation.

• Hydroelectric power is generated by burning fossil fuels

• Hydroelectric power generation involves wind turbines

• The process of hydroelectric power generation uses solar panels

• The process of hydroelectric power generation involves damming a river to create a reservoir, controlling the flow of water through turbines, which spin generators to produce electricity.

Why is nuclear energy considered controversial?

• Negative impact on wildlife

• Limited availability of uranium

• Safety concerns, radioactive waste disposal, potential accidents, and risk of proliferation.

• High cost of construction

What is biomass energy and how is it produced?

• Biomass energy is energy derived from organic materials such as wood, crops, or waste. It is produced through the process of burning these materials to generate heat or converting them into biofuels.

• Biomass energy is generated through nuclear reactions.

• Biomass energy is produced by harnessing wind power.

• Biomass energy is extracted from fossil fuels like coal and oil.

Discuss the impact of fossil fuels on the environment.

• Fossil fuels contribute to climate change by releasing carbon dioxide and other greenhouse gases when burned, leading to global warming and sea level rise. They also release pollutants like sulfur dioxide and nitrogen oxides, which contribute to smog, acid rain, and respiratory issues. Extraction and transportation of fossil fuels can harm ecosystems and wildlife habitats.

• Burning fossil fuels leads to cleaner air

• Fossil fuels have no impact on the environment

• Extraction of fossil fuels benefits wildlife habitats

How can individuals contribute to energy sustainability?

• By using outdated and inefficient appliances

• By ignoring renewable energy sources and relying solely on fossil fuels

• By reducing energy consumption, using energy-efficient appliances, opting for renewable energy sources, practicing energy conservation habits, and supporting policies that promote sustainable energy practices.

• By wasting energy without considering the consequences
