green energy
Using alternative sources of energy are encouraged in a developing country, although fossil fuels are primary origin by others. This is because fount power more green for the environment and high efficiency.
To make the sphere becomes sanitary, some countries are using the supernumerary fountain of energies that could increase citizen healthy. I highly agree since alternative energy does not use dangerous additive materials. In 2018, Australia changes its energy sources from fossil fuels to wind energy, and it not only makes the local temperature more stable at 32oC in the summer season, but also reduces the carbon dioxide contained in the air. The number of gas emissions in the last years decreases from 300 ppm to 238 ppm, and it is in line with reduced number of respiratory diseases in Melbourne.
High efficiency is owned by alternative sources of energy that could increase student interest in conducting research on this energy. I really agree, since the number of power is increased, and its reduces energy conversion time. Perovskite photovoltaic that utilize solar energy was used in United State of America, which gives electrical energy for 200 houses. By combining with Dye Sintesize Solar Cell (DSSC) of carrot, increasing conversion point of energy power until 20%, saving on lithium-ion batteries that can survive more than 24 hours, resulting the energy can wear on the night that no sunlight.
To conclude, some countries that use alternative founts of energy are increase efficiency and making environment more clean compare to fossil fuels. Therefore, as teenagers must minimalize energy using by turn off the lamp if people does not use it.
