A biofuel is an energy source that comes from living organisms or from waste. They produce and is therefore from a biological process as opposed to a geological one such as fossil fuels.
The people alive now know one thing, may be we will be last living creatures who considered fossil fuels as the only source of energy available on this planet.
climate change weighs largely on the mind of policymakers trying to find fast ways to reduce carbon emissions and transition the transportation sector away from oil.
Biofuels have inherent advantages as they work with internal combustion engines already in most cars. The push for bioenergy extends beyond transportation fuels to the harvest of trees and other sources of biomass for electricity .After Some research suggests that bioenergy could meet 20 percent of the world’s total annual energy demand by 2050.The only way that biofuels could help reduce emissions by reserving additional land not currently acting as a carbon sink to be used for biofuel production. This is a probability for specific types of biomass for example, algae grown in ponds or liquids that do not absorb CO2 alone,3 but large-scale biofuel production this way seems unlikely.
There are good alternatives to bioenergy made from a land like solar photovoltaic (PV) cells convert sunlight directly into energy that people can use, much like bioenergy, but with greater efficiency and less water use.On the other hand three-quarters of the world’s land, solar PV systems today can generate more than 100 times the usable energy per hectare as bioenergy. Because electric motors can be two to three times more efficient than internal combustion engines.
There are different ways one can contribute with the environment and reduce carbon emissions. One thing we are responsible for is our own homes.Solar panels, heat pumps and boilers are good options if we are willing to make our home more sustainable and less harmful to the environment. The world’s land is not a ifinite resource. As Earth becomes more crowded, fertile land become ever more valuable for food, timber and carbon storage—things for which we don’t have an alternative source.
