Buildings are one of the largest consumers of energy in the world. This is because of the importance of lighting as well as the need for electrical power to power various gadgets within the building. Space heating in the colder periods of the year, coupled with the need for air conditioning in the hot periods also contributes to energy demand. Hot water supply is normally supplied by geysers and most geysers are electrical and increase energy demand and carbon emissions.
However, there is now a global shift towards solar geysers. These geysers harness solar thermal energy. In addition to saving energy, solar geysers reduce the cost of running a home. Energy savings result in financial savings and hence should be taken seriously.
Lighting solutions have also been substituted by the use of natural lighting and orienting buildings in the direction from which light can come through and illuminate areas. Instead of roofing whole parts of buildings with tiles, there are some innovations in skylights, which can allow light to enter. Extreme caution should be taken if anyone considers skylight glazed spaces in the home because of the possibility of water leakages and moulding. If properly installed, they can create an ambient environment that is well lit and avoids darkness. In addition, they help to lower the energy bill.
Most new houses are also having solar systems which are grid tied. This allows the excess power to be put onto the grid and benefit from net metering. Generating your own power can give energy independence, reduce costs associated with energy as well as facilitating energy security.
