ENERGY RESOURCES  WHAT ARE ENERGY RESOURCES Energy resources are materials or elements that can be used to produce energy, which can be in the form of heat, electricity, or mechanical energy.

Unlike fossil fuels, these resources are sustainable and do not deplete over time. They are eco-friendly, reducing pollution and greenhouse gas emissions.  Description: Solar energy converts sunlight into electricity using SOLAR photovoltaic cells in solar panels. Advantages: It is abundant, environmentally friendly, and requires low maintenance after installation. Disadvantages: Installation costs are high, and energy production depends on weather and daylight.  Description: Wind energy is generated by converting the kinetic energy of moving air into electricity using wind turbines WIND Advantages: ENERGY It is sustainable, cost-effective in windy areas, and produces no direct emissions. Disadvantages: Turbines can be noisy, require specific locations, and may impact bird and bat populations.  Description: Hydroelectric power uses flowing or falling water, often through dams, to generate electricity. Advantages: HYDROELECTRIC It is a reliable and renewable energy source that ENERGY can also help with water storage and irrigation. Disadvantages: Building dams is expensive, can displace communities, and disrupt aquatic ecosystems.  Description: Geothermal energy is heat energy from the earth—geo (earth) + thermal (heat). Geothermal resources are reservoirs of hot water that exist or are human-made at varying temperatures and depths below the earth's surface. GEOTHERMAL Advantages: ENERGY Geothermal energy is a renewable source of energy that comes from the Earth's mantle. Disadvantages: High upfront costs: Geothermal energy is expensive to tap into, with a 1 megawatt capacity plant costing around $2–$7 million.  Description: is a clean, renewable energy source. Its initial energy comes from the sun, and plants or algae biomass can regrow in a relatively short amount of time. Trees, crops, and municipal solid waste are consistently available and can be managed sustainably Advantages: BIOMASS Carbon footprint: Biomass energy has a carbon footprint of zero and releases lower net carbon dioxide emissions than coal and gas. Disadvantages: Cost: Biomass can be expensive to gather, transport, and store. Space: Building biomass energy plants for large-scale electricity production can require a lot of land. NON- RENEWABLE non- renewable are energy that come from a finite amount of sources that will soon run out or cannot be replenished in our and future lifetimes. Most nonrenewable energy sources are fossil fuels: coal, petroleum, and natural gas. Carbon is the main element in fossil fuels.  Description: FOSSIL Fossil fuels energy sources that come from the remains of plants and animals that died millions of years ago Advantages: FUELS High energy density: Fossil fuels can produce a large amount of energy per unit mass, making them efficient for power generation. Disadvantages: Once used, fossil fuels cannot be replenished on human timescales, leading to depletion over time. Greenhouse gas emissions: Burning fossil fuels releases carbon dioxide and other greenhouse gases, contributing to climate change.  Description: NUCLEAR Nuclear energy is a form of energy released from the nucleus, the core of atoms, made up of protons and neutrons. This source of energy can be produced in two ways: fission – when nuclei of atoms split into several parts – or fusion – when nuclei fuse together. ENERGY Advantages: Low carbon footprint: Nuclear power produces zero-carbon emissions and emits much lower greenhouse gases than coal. Reliable: Nuclear power is a reliable energy source Disadvantages: Nuclear accidents: There is a risk of nuclear accidents, such as those that occurred at Chernobyl in 1986 and Fukushima in 2011. These accidents can release radioactive waste that can cause lasting health issues or death. Radioactive waste: Nuclear power plants produce radioactive waste that is harmful to humans and can take thousands of years to dispose of safely.  h e T nd EGROUP 1
