2. Green Building Solution In places with large landed properties, there can be a home geothermal heating and air-conditioning centre around a pipe with fluid buried deep in the ground The earth’s temperature underground is consistent, thus geothermal energy can be useful during cold climates Also, hot water can be cooled easily by flowing the water down the pipes and heat will be lost into the surroundings out of the pipe through the cool underground, and then directed up to the house again
3. Green Building Solution Though this may be an troublesome method to build the system underground, at the same time very time-consuming, but the cost of an air-pipe system is quite low Furthermore, it is both good in the long run and effectiveness, unlike the use of solar panels which depends greatly on the weather, which is inconsistent
4. Home energy-saving methods Do not run unneeded lights and fans, and restrain from air-conditioning, which is much more energy-consuming Green building solution In some places, air-ventilation systems can be built underground Air is flown into pipes, either to lose heat or to gain heat, then flown back into the house, with electricity only used for the moving fans
5. Improved methods Solar panels are being improved based on the knowledge of an atom Quantom dots are being used to confine electrons to a smaller space, so that more solar cells can be fitted into solar panels Multi-exciton generation(MEG) is also being used to allow one electron to transfer light energy absorbed to more electrons In this way, solar panels will be able to generate more electricity
6. Renewable methods University of Minnesota researchers are getting close to making renewable petroleum fuels, using bacteria, sunlight and carbon dioxide They are trying to make the proteins from the fatty acids produced by bacteria to make ketones which can be used to cracked to make hydrofuels The hydrofuels are made by using sugars made from one bacterium, Synechococcus, by taking in carbon dioxide, then feeding the sugars to another bacterium,Shewanella,which will turn carbon dioxide produced by burning of fossil fuel petroleum into hydrofuel
7. Renewable methods This method is very efficient as carbon dioxide is a raw material, thus that means carbon dioxide, being a greenhouse gas, has to be removed from the environment, thus slowing the impact of global warming Secondly, with renewable petroleum fuel, there will be less usage of natural resources, thus saving the earth
8. Easy green methods Put a drop of food-colouring into the toilet tank, and if the colour starts appearing in the bowl, it shows a leak Water will be wasted if the leak is not repaired There will be more water pollution in nearby lakes, rivers, or local watersheds However, this method is also applicable to Singapore, as the government has been emphasizing on water conservation
9. Easy green methods Take quick showers instead of a bath Water can be conserved and water bills will not be so high Collect rainwater for garden uses Water used for washing rice, or washing the clothes, can be used to water the plants In this way, water can be conserved
10. Most importantly, urge everyone consistently to use easy energy saving methods at home, with everyone doing their part, there won’t be such a huge strain on people to invent complicated stuff to reduce energy usage!
