"Energy is sustainable if it 'meets the needs of the present without compromising the ability of future generations to meet their own needs.'"
Ensuring access to affordable, reliable, sustainable, and modern energy for all.
Renewable Energy: Any energy source that comes from renewable and natural resources such as wind, solar, and hydro.
Energy Efficiency: Measures taken to reduce the amount of energy used in a process or a building.
Green Buildings: Structures that are designed to use energy and resources more efficiently than traditional buildings.
Bioenergy: Fuel derived from organic matter such as agricultural waste, wood, and biofuels.
Energy Storage: Technologies that can store energy for later use such as batteries and other energy storage systems.
Carbon Capture and Storage (CCS): Technology and strategies to capture CO2 from industrial processes and store it underground.
Smart Grid: An advanced power delivery system that improves efficiency, reliability, and cost-effectiveness of delivering electricity.
Energy Access: Increasing access to energy resources in areas where the population has limited access to it or no access at all.
Electric Vehicles: Cars, trucks, bikes, and other vehicles that run on electric power instead of gasoline.
Waste-to-Energy: The process of converting waste into usable energy.
Off-grid Energy: Using renewable energy systems in remote locations where grid access is limited or unavailable.
Carbon Offsetting: Purchasing carbon credits to offset the carbon emissions generated from a company's operations.
Energy Poverty: Addressing the lack of access to affordable and reliable energy among low-income households.
Sustainable Transportation: Using sustainable sources of energy for transportation, such as electric cars, buses, and trains.
Green Jobs: Jobs created through the growth of the green economy, including in sectors like renewable energy, energy efficiency, and waste management.
Solar Energy: This type of energy involves using solar panels to convert sunlight into electricity.
Wind Energy: Wind turbines are used to generate electricity from the wind, which is one of the most abundant sources of energy.
Hydro Energy: This involves using the force of moving water (e.g. rivers, tides, and waves) to generate electricity.
Geothermal Energy: This type of energy involves tapping into the Earth's internal heat to generate electricity.
Biomass Energy: This involves using organic matter such as wood, crops, and waste to generate electricity.
Biofuels: These are fuels made from renewable sources like biomass or waste, which can replace traditional fossil fuels.
Wave Energy: This involves capturing the energy in ocean waves to generate electricity.
Tidal Energy: This involves using the energy from the tides to generate electricity.
Hydrogen Fuel Cells: These generate electricity by combining hydrogen and oxygen through a chemical reaction.
Sustainable Nuclear Energy: This refers to the use of nuclear reactors that produce much less waste and are much safer than traditional nuclear reactors.
Energy Storage: This involves using batteries or other methods to store excess energy generated by renewable sources, for use when needed.
Micro Hydropower: This involves using small-scale hydroelectric power systems that can be installed in rivers or other waterways to generate electricity.
Solar Thermal Energy: This involves using mirrors or other reflecting surfaces to concentrate sunlight and generate heat, which can then be used to generate electricity or provide hot water.
Rooftop Solar: This involves installing solar panels on the roofs of buildings to generate electricity for local use.
Community Solar: This is a shared solar system where multiple households or businesses share the benefits of solar power.
"Considerations of environmental aspects such as greenhouse gas emissions..."
"Renewable energy sources such as wind, hydroelectric power, solar, and geothermal energy..."
"Renewable energy sources such as wind, hydroelectric power, solar, and geothermal energy are generally far more sustainable than fossil fuel sources."
"Some renewable energy projects, such as the clearing of forests to produce biofuels, can cause severe environmental damage."
"Nuclear power is a low-carbon source whose historic mortality rates are comparable to those of wind and solar, but its sustainability has been debated because of concerns about radioactive waste, nuclear proliferation, and accidents."
"Switching from coal to natural gas has environmental benefits, including a lower climate impact..."
"Carbon capture and storage can be built into power plants to remove their carbon dioxide (CO2) emissions, but this technology is expensive and has rarely been implemented."
"Fossil fuels provide 85% of the world's energy consumption..."
"Around 790 million people in developing countries lack access to electricity..."
"The transition to a low-carbon energy system would have strong co-benefits for human health. Pathways exist to provide universal access to electricity and clean cooking in ways that are compatible with climate goals while bringing major health and economic benefits to developing countries."
"These pathways include phasing out coal-fired power plants, producing more electricity from clean sources such as wind and solar, and shifting towards using electricity instead of fossil fuels in sectors such as transport and heating buildings."
"To accommodate larger shares of variable renewable energy, electrical grids require flexibility through infrastructure such as energy storage."
"Well-designed government policies that promote energy system transformation can lower greenhouse gas emissions and improve air quality."
"Policy approaches include carbon pricing, renewable portfolio standards, phase-outs of fossil fuel subsidies, and the development of infrastructure to support electrification and sustainable transport."
"Funding the research, development, and demonstration of new clean energy technologies is also an important role of the government."
"Wind and solar energy generated 8.5% of worldwide electricity in 2019."
"The Intergovernmental Panel on Climate Change (IPCC) estimates that 2.5% of world gross domestic product (GDP) would need to be invested in the energy system each year between 2016 and 2035 to limit global warming to 1.5 °C (2.7 °F)."
"Policy approaches include carbon pricing, renewable portfolio standards, phase-outs of fossil fuel subsidies, and the development of infrastructure to support electrification and sustainable transport."
"Well-designed government policies that promote energy system transformation can lower greenhouse gas emissions and improve air quality."
