Rio+20 is the shorthand name for the United Nations Conference on Sustainable Development, which is being held 20-22nd June 2012 in Rio de Janeiro, Brazil.
There are two major considerations to consider when renovating to ensure maximum energy efficiency is achieved.
Hybrid solar lighting technology is a technology that is capable of collecting sunlight and distributing the collected sunlight into the interior of a building using optical fibers.
Using the energy from the sun to heat water reduces household hot water bills by at least 65% per year. This could accumulate to savings of thousands of dollars over the lifetime of the solar hot water system.
Insulation is vital in keeping your home cool in the summer and warm in the winter seasons. A home that has been well insulated is at least 7 degrees cooler in summer and 10 degrees warmer in winter.
Vehicle exhaust emissions are created when the air-fuel mixture burning inside internal combustion engines releases carbon dioxide back into the atmosphere.
Hybrid electric vehicles (HEVs) combine the power from an internal combustion engine with the battery and electric motor from an electric vehicle.
Carbon dioxide and methane generated as a result of the decomposition of solid waste in landfills are known as landfill gas. Both gases are greenhouse gases that lead to global warming.
