Green Energy is generated from alternative energy sources that get powered by various natural events and cannot get depleted with use. The 3 main sources of Green Energy are water, wind and solar energy that can limit the dependence on fossil fuels dramatically. Falling water has had been in use to power dams so as to produce electricity. Even though dams generate clean energy, they leave a negative impact on the ecosystems surrounding the area.
Wind power is harnessed using wind mills where the movements are transformed into electricity. The energy produced by wind mills is both renewable and clean. And, solar energy is generated using solar panels that transform the sun’s light into electricity that can be used to power homes, industries, vehicles and can be used for other purposes.
Green Energy Models
Green Energy models are complete demand and supply systems based upon renewable energy unlike energy produced from fossil fuels and nuclear energy. Green Energy models consist of both supply and demand. The shift from conventional fossil fuel and nuclear-based models to Green Energy systems requires well coordinated changes in the following:
Demand technologies for conservation of energy
Improvement of efficiency in supply systems
Integration of irregular Green Energy sources like wind power
Green Energy systems consist of both the technologies that carry out the conversion of energy from one from to another and storage technologies that save energy from hour to hour.
Large-Scale Integration
The integration of Green Energy sources with existing energy models at a large-scale involves meeting the some challenges. The challenges include the coordination of fluctuating as well as irregular production of renewable energy along with the rest of the system. Meeting these challenges is especially important with regard to electricity systems because such systems require a precise balance between supply and demand.
Energy System Analysis Models
The large-scale integration of Green Energy and the designing of 100% green power systems require a calculation of fluctuations in sources of renewable energy on an hour to hour basis. It is also important to include analysis of advanced storage and conversion technologies in the models.
Green Energy technology
The drive for Green Energy standards is an important issue today. Therefore understanding the options are going to help understand the direction in which the Green Energy market is headed.
Solar Power
In solar power systems, the sun’s radiation is absorbed by solar cells, also known as photovoltaic cells. The process consists of the displacement and movement of electrons for absorbing sunlight and creating electricity. Then, there are solar energy systems that utilize large-scale mirrors for heating water, or generating steam and high temperatures, used for turning generators.
Wind Power
Generation of wind power is a simple process, where a wind turbine transforms wind’s kinetic energy to mechanical energy for generating electricity. This energy is passed through a generator for converting to electricity, and then it is transmitted through the grid. The largest wind power plants in include the Vankusawade Wind Park in Satara Maharashtra, Cape Comorim, Tamil Nadu, Kayathar Subhash in Kayathar, Tamil Nadu, Muppandal Wind in Tamil Nadu and Ramakkalmedu in Kerala. The unique thing about wind energy is that it offers incentives to farmers who provide their land for construction of wind turbines. This Green Energy source has the highest potential as long as extensive adoption because of large area of land has steady wind for harnessing.
Geothermal Power
Geothermal power is another Green Energy source where underground heat is trapped and used to build energy when it rises at the surface. When the underground heat leads to the creation of natural steam or hot water, this energy is harnessed for running a steam turbine for generation of electricity. Geothermal energy was first used in Italy in the early 18th century.
Biomass Power
A highly versatile form of Green Energy, biomass fuel is burned to heat water in boilers and a steam turbine is used for creating electricity. Unique results are being gained from agricultural research, such as the use of cow manure in dairy farms for generating energy.
Hydropower
Around 73% of all the Green Energy is estimated to come from the power of water, also known as hydropower. Flowing water has mechanical energy, and when water is forced through penstock for turning a generator it helps in producing electricity. Tidal energy and wave energy are other forms of green power produced through wager. Research is still underway to harness energy from the motion of the ocean. The Bhakra Nangal Dam is the largest dam in India. Built on the Satluj River, this is also the second largest dam in Asia. Over 1,000 MV of electricity is generated from this dam that consists of 10 heavy turbines.
