because there are still manynegatives that need to be dealt with when it comes to using solar energy. Suchas the environmental impact of manufacturing the panels themselves, the carbonfootprint of producing these solar plates is a work in progress. Depending onthe size and wattage of the panels chosen for instalment they can cost anywherefrom $15,000 to $35,000 for your average house and can take anywhere from 10 to30 years to recoup the initial investment. If installed early on in your houseowning life, it is totally worth it in the long run, but for others not so muchbecause they may never wreak the benefits of money saving by the time they payoff the instalment costs – again another work in progress but will only becomemore affordable and cost effective as time goes on.
The manufacturing cost ofthese panels isn’t as drastic as you’d think- it all depends on somewhat sizebut more importantly wattage. The same size panel could have a completelydifferent wattage than the one next to it. It depends on the costumers needsand wants by analysing their personal energy consumption. They also work just as fine if not greaterfor houses with smaller square footages for the sole reason that a smallerhouse requires significantly less energy. Another key issue is the ability tocollect energy under certain conditions like poor weather, or shifting sunraysthroughout the day. However some innovative ideas have been worked on overrecent years: China has been creating a sphere like solar cell that can notonly capture energy from every angle but also reflective energy. If invested properly and usedin conjunction with other green technologies solar power has the ability tochange the way of life, as we know it. Solar energy is just one of manytechnological advances being used today to create a better living environmentfor not only us but also the following generations to come.
Another example isusing more eco-friendly building materials during construction; at one point intime every structure was build only using safe material found from the landsuch as straw, rock, dirt, clay, etc. But my favourite green technology that isbeing used today are green roofs, this is a building that is partially orentirely covered with vegetation and a growing medium, planted over a waterproofing membrane. These roof systems are great because they help reduce thedamage and harm caused by urban development on the ecosystem. By building largeconcrete cities we destroy natural habitats…these roofs although not ideal,still give other life more area to live and feed.
There are so many otherreasons as to why a green roof in the way to go especially in warmer climateswhere you can truly wreak the benefits. Some solid reasons as to why investingin a green roof are as listed:Inexpensive – $5 to $15 a squarefoot, and being so protected from the harsh elements of the sun and weatherextremes the roof lasts longer. Storm water Management – Green roofsare designed to be able lessen the negative effects of rain and storm water inmany ways. They retain rainfall, and slow the flow of water into the sewage systemsthat ultimately carries waste into our clean bodies of water. Lower energy costs – Althoughminimal, it has been proven that these naturally insulated roofs help reducethe amount of heat loss from within.
But more importantly help keep buildings coolerin the summer because of the reflective abilities of plant leaves. So in conclusion “green technology”is taking over. It won’t be long until building regulations and codes requirehouses to be built completely green, and for the sake of our environment Ican’t wait until that day. But until then, combining methods and ideas we’vedeveloped thus far in green technology is all that we can do for now.
