How Green is Green Technology?
September 10th, 2009Green technology is technology that is compatible with the environment. For green power technology, it may mean the use of sustainable forms of energy. Oil and coal based power generation is never green because it is based on extracting something from the earth and not replacing it. Oil and coal technology may be improved to make it less environmentally damaging but it can never be green.
Oil and coal represents dead animal and plants whose organic makeup have been converted into petroleum or coal. When we burn oil and coal to power our electric plants or drive our cars, we release CO2 which is the result when organic stuff is burnt. We have been driving our cars for years now and we have allowed coal and oil based power plants to release CO2 into the environment. The effect is that we have been burning the equivalent of millions of years of plant and animal growth into a relatively short amount of time, which is the 20th century.
Even if technologies to reduce the amount of CO2 emitted exists or are being developed, sustainable forms of power generation is always better because no greenhouse gases are generated. Because we are still a long way off from deriving much of our energy sources from sustainable means, we have to therefore change our way of life so that it is not so much dependent on fossil energy.
Fuel production based on biomass such as the production of bioethanol and biodiesel is not green because scarce land resources are used for producing fuel and not for food. It has been estimated that using biofuels to reduce the amount of emissions in Britain by half, requires twice the land area of the entire English archipelago to produce sufficient amounts of biodiesel.
When we use green energy and change our lifestyle, we are literally making the earth greener because less resource extraction takes place. Less mining, less cutting of trees naturally means a greener world.
