  • Hydroelectric energy is generated from the energy of flowing rivers and turbines.
  • Geothermal energy uses heat stored within the Earth's crust to generate electricity.
  • Disadvantages of hydroelectric power include high initial capital cost, environmental impacts on river ecosystems, and potential loss of life during dam construction or failure.
  • The advantages of hydroelectric power include being renewable, reliable, and having low operating costs.
  • Wind turbines convert kinetic energy from moving air into mechanical energy to generate electricity.
  • Solar power is the most abundant source of energy on Earth and can be harnessed through photovoltaic cells or concentrated solar power systems.
  • The main types of renewable energy are solar, wind, hydroelectricity, geothermal, tidal, wave, biomass, and biofuels.
  • Renewable energy is environmentally friendly as it does not pollute the air or water and does not produce greenhouse gas emissions.
  • Renewable energy technologies collect and generate energy from renewable sources or regenerate energy from renewable sources and generate electricity.
  • <S>:Renewable energy sources are naturally replenished and sustainable energy sources such as sunlight, wind, rain, tides, and geothermal heat.
  • Solar energy is derived from the sun's radiation and can be converted into electricity or used for heating and cooling.
  • Biomass energy involves burning organic matter such as wood, crops or waste products to produce steam that drives turbines.
  • Advantages of geothermal energy include low operating costs, no greenhouse gas emissions, and minimal land use requirements.
  • Advantages of geothermal energy include being renewable, reliable, and having low greenhouse gas emissions.
  • Solar panels convert sunlight into electrical current through photovoltaic cells.
  • Wind power harnesses wind energy using large turbines with blades attached to generators.
  • Disadvantages of geothermal energy include limited availability due to location-specificity, high upfront investment costs, and potential negative effects on local communities.
  • Biomass refers to organic matter that can be used as fuel.
  • Advantages of wind power include being clean, renewable, and having no fuel costs once installed.
  • Advantages of wind power include being clean, abundant, and having no fuel costs once installed.
  • Biomass refers to organic matter that can be used as fuel, such as wood, agricultural waste, and municipal solid waste (MSW).
  • Photovoltaics are devices that directly convert sunlight into electrical current.
  • Non-renewable resources cannot be replenished at the same rate they are used up.
  • Advantages of renewables include that they do not run out like fossil fuels, have lower running costs than non-renewables, and are more sustainable.
  • Disadvantages of wind power include intermittency due to weather conditions, noise pollution, and visual impact on landscapes.
  • Renewables have become increasingly popular due to concerns about climate change and depletion of fossil fuels.
  • Advantages of renewable energy sources include being cleaner than non-renewable sources, reducing greenhouse gas emissions, and providing local jobs.
  • Wind energy is generated by the movement of wind turbines that convert kinetic energy to electrical energy.
  • Non-renewable resources include coal, oil, natural gas, nuclear fuel, and other finite resources that cannot be replaced once used up.
  • Solar panels use photovoltaics to convert sunlight directly into electrical current.
  • Wind power uses wind turbines to convert kinetic energy into mechanical energy which generates electricity.
  • Disadvantages of renewables include their intermittency (they cannot always supply enough energy), their variability (the amount of energy produced depends on weather conditions), and their location (some sources may only be available in certain areas).
  • Fossil fuels such as coal, oil, and natural gas are non-renewable resources that have been formed over millions of years by the decomposition of organic matter under high pressure and heat.
  • Disadvantages of renewable energy sources include intermittency (depending on weather conditions), high upfront investment costs, and visual pollution caused by large structures such as wind farms.
  • Hydroelectric power plants harness the kinetic energy of falling water to turn turbines and generate electricity.
  • Disadvantages of geothermal energy include high upfront capital costs, limited availability due to location-specificity, and potential environmental impacts.
  • Hydroelectricity involves generating electricity using moving water, either through damming rivers or utilizing ocean currents.
  • Coal is a solid fossil fuel made mostly of carbon with small amounts of sulfur, nitrogen, oxygen, and other elements.
  • Fossil fuels are non-renewable resources formed over millions of years by the decomposition of organic matter under high pressure and temperature conditions.
  • Wind power uses wind turbines to generate electricity by converting kinetic energy into mechanical energy.
