Some energy efficiency developments around the world

New energy efficiency measures seem to be leading the way to reduce carbon dioxide emissions. Be it manure that generates electricity in Beijing’s chicken farm or Spain’s solar powered bubble building, more and more energy efficiency measures are coming forth to reduce the dependence on fossil fuels across the world.

Spurred on by new ways to improve energy efficiency, countries across the world are rising to the occasion and formulating new initiatives in the realm of energy efficiency measures. Since time immemorial, manure has been one of the most abundant resources for fuel that is readily available on the earth’s surface. Traditionally, manure has been the focal point because it is an essential ingredient that increases soil fertility. Currently, it is one of the most efficient storehouses for energy production.

A chicken farm located in north Beijing has already started using chicken manure to generate power and electricity. The chicken farm started with 220 tons of manure and 170 tons of wastewater, both of which get collected from 3 million chickens everyday. Results now indicate that this chicken farm will soon replace a coal-fired plant in Beijing. This has the potential to reduce 95,000 tons of carbon dioxide emissions every year. Better still, this new form of manure energy will also drastically ease electricity shortage in the region.

Spain has launched a project called Solar Powered Bubble Building. This project comprises buildings that will be made from concrete insulate, with a layer of green plants and herbs covering the top. A glass sheet will be placed atop the building to ensure that the building remains warm in winters and gives a cooling effect during summer months.

The proposed Solar Powered Bubble Building is heavily dependent on solar energy. Interestingly, rainwater and sewage that is generated from the building will be recycled effectively for reuse.

Cement production has widely been reported as being the primary culprit in polluting the environment. California-based Calera is a company that is developing a process to collect 90% of the carbon dioxide emitted from power plants. Claiming to have the finest carbon capture and storage capacity, Calera’s process is a highly effective way of converting carbon dioxide into carbonic acid and then producing carbonate from this.
