The world’s population has grown exponentially
since the second world war, and there is currently pressure on
available land and natural resources. As a society, we will
eventually be faced with the depletion of our most widely used
source of energy, the non-renewable fossil fuels. Scientists from
whole world are coming to the conclusion that the present rate of
energy consumption in the world will not be sustainable in the
future. There are many ways in which scientists are taking steps
to reduce consumption such as developing new types of vehicles,
energy sources, recycled materials, and designing
environmentally friendly buildings. These environmentally
friendly buildings are also known as “green” buildings. We can
reduce our dependence on fossil fuels and other resources by
constructing buildings that use recycled materials in their
construction, are more energy efficient, produce oxygen, purify
pollutants, and generate energy on site using environmentally
friendly means. One of the major benefits of green buildings is
that they require less energy to operate. This has the effect of
lowering energy costs and reducing dependence on the local
utility. Some technologies may have a higher initial cost than the
conventional alternatives, but the increased efficiency of a green
building can offset this cost over the lifetime of the building.
