What is renewable energy?
Explanation: The correct answer is C) Energy obtained from sustainable sources. Renewable energy refers to energy derived from sources that are naturally replenished, such as sunlight, wind, water (hydro), geothermal heat, and biomass. Unlike fossil fuels and nuclear energy, which have finite supplies, renewable energy sources are considered sustainable and have lower environmental impacts.
Which of the following is a renewable energy technology?
Explanation: The correct answer is C) Solar photovoltaic (PV) panels. Solar PV panels convert sunlight directly into electricity and are a widely used renewable energy technology. They consist of solar cells that capture photons from the sun and generate an electric current. This technology harnesses the abundant solar energy resource and has minimal environmental impacts compared to fossil fuel-based technologies like coal-fired power plants, natural gas extraction, and oil refineries.
Why is the transition to renewable energy important?
Explanation: The correct answer is A) To reduce greenhouse gas emissions. The transition to renewable energy is crucial for mitigating climate change by reducing greenhouse gas emissions. Renewable energy sources have lower or zero emissions compared to fossil fuel-based energy sources, which are the primary contributors to greenhouse gas emissions. By transitioning to renewable energy, we can mitigate climate change, improve air quality, enhance energy security, and foster sustainable economic development.
What is an example of a renewable energy policy?
Explanation: The correct answer is D) Feed-in tariff for solar power. A feed-in tariff is an example of a renewable energy policy that encourages the adoption of renewable energy technologies. Under a feed-in tariff, renewable energy producers are guaranteed a set payment rate for the electricity they generate and feed into the grid. This policy incentivizes the development of renewable energy projects, such as solar power installations, by providing long-term contracts and financial support. Subsidies for coal mining, carbon taxes, and expansion of oil drilling permits, on the other hand, are not renewable energy policies but rather measures related to fossil fuel-based energy sources.
What are some benefits of the renewable energy transition?
Explanation: The correct answer is C) Energy security and independence. The renewable energy transition brings numerous benefits, including improved energy security and independence. By diversifying the energy mix and reducing dependence on fossil fuel imports, countries can enhance their energy security and reduce vulnerability to supply disruptions and price volatility. Furthermore, renewable energy sources are inherently more abundant and sustainable compared to finite fossil fuel resources, thus reducing the risk of resource depletion. Additionally, renewable energy helps mitigate climate change and improve air quality, leading to various health and environmental co-benefits.
