Energy is a phenomenon that occurs as a result of changes in properties such as the position, speed, position or state of an object during transactions between materials. Energy can be found in different forms such as heat, mechanical, electrical, electromagnetic, nuclear and chemical and can be defined in relation to the work an object can do. Energy is needed for many different purposes, such as electricity generation, heating, lighting and transportation for human use.
Sustainable energy is renewable energy resources that emerge as a result of efforts and technological developments to meet the energy needs of people by using natural resources. Sustainable energy sources are produced by the continuous renewal or recycling of natural resources on earth. These resources include solar energy, wind energy, hydroelectric energy, geothermal energy, biogas and biomass energy.
These alternative energy sources are being used more and more to meet the energy needs of the world’s countries. It is also used to keep environmental impacts to a minimum and to help prevent global warming and other environmental problems. The use of sustainable energy sources reduces the amount of waste in energy production and initiates a trend towards environmentally friendly energy production.

Sustainable Energy Sources
Sustainable energy resources are energy resources that naturally consist of renewable resources and aim to respond to priority issues such as global climate change and environmental protection. Alternative energy solutions also offer alternatives to conventional energy sources such as fossil fuels and nuclear energy as well as sustainable energy sources in order to prevent the depletion of natural resources despite the increasing global energy demand. Among the sustainable energy sources;
Solar energy; It is the most common sustainable energy source used to convert sunlight and heat into electrical energy. Solar energy is produced with the help of solar panels.
Wind power; It is produced by turbines powered by wind energy.
hydroelectric energy; energy produced using water. Hydropower is produced with the help of dams or hydroelectric power plants.

Geothermal energy; It is the energy produced by using the heat inside the earth. Geothermal energy is produced from underground hot springs and volcanic activities.
biogas; It is the gas formed as a result of the anaerobic (oxygen-free) decomposition of organic wastes. It is produced by anaerobic fermentation of materials such as animal waste, agricultural waste and organic waste.
Bioenergy; Bioenergy is produced with the help of organic wastes such as plant and animal waste.
Ocean Energy; Ocean energies such as wave, mareomotric and thermal energy are produced.
