Energy resources 2.4

What are the different types of energy resources?

• Coal, wind, solar

• Biomass, tidal, wave

• Hydroelectric, geothermal, natural gas

• Fossil fuels, nuclear energy, renewable energy sources

Explain the concept of renewable energy and provide examples.

• Renewable energy is energy that is collected from renewable resources, which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat.

• Renewable energy includes nuclear power and natural gas.

• Examples of renewable energy are coal and natural gas.

• Renewable energy is energy collected from fossil fuels like coal and oil.

What are the advantages of using renewable energy sources?

• Renewable energy sources are sustainable, reduce greenhouse gas emissions, and decrease dependence on fossil fuels.

• Renewable energy sources are unreliable and cannot meet the energy demand.

• Renewable energy sources are expensive and unaffordable for most people.

• Renewable energy sources require a lot of space and are not practical for urban areas.

Discuss the importance of energy efficiency in today's world.

• Energy efficiency is not a cost-effective solution for reducing energy consumption

• Energy efficiency helps to reduce energy consumption, lower greenhouse gas emissions, and save money on energy bills.

• Energy efficiency only benefits large corporations and does not affect individuals

• Energy efficiency has no impact on the environment or energy consumption

How can energy be conserved in everyday activities?

• By increasing unnecessary energy consumption

• By leaving all lights and appliances on all the time

• By turning off lights and appliances when not in use, using energy-efficient appliances, and reducing unnecessary energy consumption.

• By using energy-guzzling appliances

What are the challenges associated with the use of renewable energy?

• Consistent supply, low environmental impact, low maintenance costs, and easy integration into existing infrastructure.

• No intermittency, low initial costs, minimal land use, and positive environmental impact.

• Low initial costs, stable supply, minimal land use, and positive environmental impact.

• Intermittency, high initial costs, land use, and environmental impact.

Compare and contrast non-renewable and renewable energy sources.

• Non-renewable energy sources are sustainable and environmentally friendly, while renewable energy sources are finite and produce pollution.

• Non-renewable energy sources are abundant and do not produce pollution, while renewable energy sources are scarce and harmful to the environment.

• Non-renewable energy sources are finite and produce pollution, while renewable energy sources are sustainable and environmentally friendly.

• Non-renewable energy sources are not harmful to the environment, while renewable energy sources are not sustainable.

Explain the concept of energy efficiency and its impact on the environment.

• Energy efficiency has no impact on the environment

• Energy efficiency helps in reducing the environmental impact by decreasing the amount of energy required for various activities.

• Energy efficiency only impacts the cost of energy, not the environment

• Energy efficiency increases the amount of energy required for various activities

What are the different ways to harness renewable energy?

• Solar, wind, hydro, geothermal, and biomass energy

• Nuclear energy only

• Coal, natural gas, and oil

• Fossil fuels and nuclear energy

Discuss the role of government policies in promoting renewable energy and energy efficiency.

• Government policies have no impact on renewable energy and energy efficiency

• Government policies provide incentives, subsidies, and regulations to encourage the use of renewable energy sources and energy-efficient technologies.

• Government policies only focus on promoting non-renewable energy sources

• Government policies discourage the use of renewable energy and energy-efficient technologies
