Geothermal Energy
Geothermal energy is the heat from the Earth and it's a clean and sustainable. Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles under the surface of the earth, and down even deeper to the extremely high temperatures of molten rock named magma. There are three main types of geothermal energy systems: Direct use and district heating system and Electricity generation in power plants and geothermal heat pumps. The steam rotates a turbine, than the turbine activates a generator, which produces electricity.in the world, there are many power plants still use fossil fuels to boil water for steam. Geothermal power plants, using the steam, produced from reservoirs of hot water found a couple of miles or more below the Earth's surface. heat exchanger-a system of pipes covered in the shallow ground near the building. In the winter, the heat pump removes heat from the heat exchanger and pumps it into the private air delivery system. In the summer, the process is converse, and the heat pump moves heat from the indoor air into the heat exchanger.
Green Energy
A substance that is converted by process into usable energy then the substance is called source of energy. One of the beneficial factors for the use of the Energy is that it is naturally generated. These sources are constantly replenished such as sunlight, wind, heat and water. The common energy sources are Biomass, Biofuels, Wind, Geothermal and Solar Energy. Renewable energy is energy that is collected from natural sources that replenish themselves over short periods of time, renewable energy resources exist over wide geographical areas. Rapid deployment of renewable energy and energy efficiency is resulting in significant energy security, climate change mitigation, and economic benefits.
Solar Energy
Solar Energy is the most promptly accessible wellspring of energy. Sun is the sources of all energies, the primary forms of solar energy are heat and light. It doesn't have a place with anyone and is, in this manner, free. It is additionally the most essential of the non-conventional sources of energy. Since it is non-contaminating and along these lines, helps in decreasing the greenhouse impact. Solar energy can likewise be utilized to meet our power prerequisites. Through Solar Photovoltaic (SPV) cells, sunlight based radiation gets changed over into DC power specifically. Solar Energy is dependable progressing at Solar Transport. Fuel production is also done with the help of high temperature from solar energy. The energy is capture, which is produced at one time and is store for future use. Solar energy free and clean energy and the solar panels can be placed on roofs of houses which makes less occupancy.
Wind Energy
The wind is a free, clean and gladly available renewable energy source. In the world, every day wind turbines are capturing the wind’s power and converting it to the electricity. The energy from the wind turns the two or three propeller-like blades around a rotor in windmill. The rotor is connected to the main shaft, and this shaft connected with the generator to create electricity. This source of power generation plays a progressively important role in the way of power in our world. Wind turbines captured the kinetic energy of the wind into mechanical power. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) in the turbines generator or can be convert this mechanical power into useful power like electricity. Now wind power technology is showing rapid growth and much more helpful than conventional power generation.by using this wind energy there is no pollution and less space occupancy and less cost effective. Wind turbines don't deliver air discharges that lead to medical issues like asthma or make corrosive rain or nursery gasses which is involves in coal handling plants.
Waste-to-Energy
Waste-to-energy or energy-from-waste is that the one of the way of generating energy within the type of electricity and heat, from the first treatment of waste, through this the un-useful amount of energy can be considerably utilized. Waste-to-energy may be a type of energy recovery process .Now a days, Most Waste-to-Energy proceeding manufacture electricity and/or heat directly through combustion, or manufacture flammable fuel goods, like gas, alcohol or artificial fuels, methanol. For new processes like the Ebara fluidization, direct smelting method and also the Thermo- select -JFE and melting technology process for waste to energy process there are vast amount of thermal treatment plants victimized. Waste to energy technology includes aging, which may take biomass and make liquor, exploitation squander plastic or natural material. Inside the aging technique, the sugar inside the waste is changed to nursery outflow and the liquor, inside the similar and general strategy, that is wont to assemble wine. Esterification is also should be possible exploitation waste to vitality innovations, and more, the consequences of this technique are biodiesel. The esteem adequacy of esterification can depend on the feedstock being utilized and each one the inverse important variables like transportation remove, amount of oil blessing inside the feedstock can be improved in the waste to energy process.
Biomass Energy
One of the most prominent and promising renewable energy Biofuels can be converted directly to the liquid fuels. Biofuels is widely used for the transportation. There are various types of Biofuels such as Ethanol, Biodiesel, Bioalcohols, Green Diesel, and Biofuel gasoline, Vegetable Oil, Bioethers, Biogas, Syngas and Solid Biomass Fuels. Ethanol and Biodiesel are the commonly used biofuels. The main aim for introducing Biofuels was to replace Gasoline, Diesel Fuel and Coal. Green Diesel, Biogas.

According to few facts, Biofuels is the only renewable energy which can replace the fossil fuels.
Sustainable Developments & Environmental Science
Supportable Advancement is the dealing with a rule for meeting human change targets while meanwhile dealing with the limit of basic structures to give the ordinary resources and natural framework organizations whereupon the economy and society depend. Reasonable vitality is spotless and can be used over a drawn out stretch of time. Not in any manner like oil subordinates and biofuels that give the weight of the universes essentialness, practical power sources like hydroelectric, sun fueled and wind has imperativeness conveyed far less contamination. Sun based vitality is for the most part used on open halting meters, street lights and the highest point of structures.
Concentrations on protecting the environment by reducing waste and pollution discipline that takes from broad scientific topics like chemistry, biology, ecology, geology, hydraulics, hydrology, microbiology, and mathematics to create solutions that will protect and also improves the health of living organisms and improve the quality of the environment.

Environmental engineering is a professional engineering Environmental engineering is a sub-discipline of civil engineering and chemical engineering to the study of the environment, and the solution of environmental problems.
Impact on Agriculture
Agricultural economics, study of the allocation, distribution, and utilization of the resources used, along with the commodities produced, by farming.In general, one can say that when a large fraction of a country's population depends on agriculture for its livelihood.
Market Trends, R&D on Renewable Energy
Government energy R&D spending in 2019 grew by 3% to USD 30 billion in 2019, and was mostly directed to low-carbon energy technologies. While the growth rate in 2019 was below that of the previous two years, it remained above the annual average since 2014. It also reflects the multi‑annual nature of many government R&D budgets, which follow cyclical trends within budget periods. For example, a main reason for the weaker growth in 2019 was the stabilisation of China’s public energy R&D spending, yet this is closely tied to the Five-Year Plan (FYP) framework in China. Certain research programmes, especially those related to coal technologies, have passed their peak spending under the 13th FYP and are now analysing results and planning for the next funding period, from 2021 to 2025. There are indications that low-carbon technologies, including hydrogen, could receive a boost in the next period.
