Renewable energy resources commonly used for building applications include solar, wind, geothermal, and biomass. Before selecting an appropriate renewable energy technology to apply to an existing building retrofit project, it is important to first consider a number of factors.
Five major renewable energy sources-
- Solar energy from the sun.
- Geothermal energy from heat inside the earth.
- Wind energy.
- Biomass from plants.
- Hydropower from flowing water.
Renewable energy in developing countries is an increasingly used alternative to fossil fuel energy, as these countries scale up their energy supplies and address energy poverty. Renewable energy technology was once seen as unaffordable for developing countries.
Mechanical, chemical, industrial and electrical engineers work in the alternative energy field. Any of the main engineering disciplines can have an alternative energy component.
According to new research by construction blog Bimhow, the construction sector contributes to 23% of air pollution, 50% of the climatic change, 40% of drinking water pollution, and 50% of landfill wastes.
These renewable energy practices save money, result in more attractive buildings, and they improve the environment and strengthen the economy by reducing the need for fossil fuels.
