Energy resources - Water maybe?
Enigin offers some great tips for reducing energy within the home here. Some of these include do it yourself electricity via using a generator, to using air again instead of air conditioning.
Another great tip is to replace old appliances. It seems the newer appliances are more cost effective in terms of energy usage. Enigin even goes so far as to quote over the lifetime of a say, a refrigerator, one can realize a saving of a whopping £3,250 over it’s lifetime! This is even though it might cost you about a £1000 to replace. The long term gains are worth it, if taking into account these figures.
Solar and wind generated products are also cost efficient in the long run. However to make a house solar powered can be quite expensive. What if you don’t get that much sun in your country? Then what? Can we make the house rain powered? Now there’s an idea! Why don’t scientists come up with that one?
You may think that this is crazy, but they have found a way to untilize both wind and solar generated electricity already! You never know the water one might be the next natural resource we could utilize for powered household needs. Not to mention, by catching the downpour, it could also be a step to conserving fresh water.
