Green! Sustainable! Energy Efficient! These are the words and phrases we see time and again in our home improvement stores. The environmentally conscious world we live in makes earth friendly green products desirable. The marketers know this and are sure to slap green and sustainable labels on everything as often as possible. Certainly, understanding the effect one has on the environment is a good thing. Conserving resources is a responsibility we all have. Plus, energy efficiency can save you money in monthly bills. Caveat Emptor. Let the green buyer beware. How can we sift through the propaganda and glittering generalities and find out what’s real and important?
The watt rating is the amount of power (amps x volts) the panel will produce in full sunlight at 77 degrees F or 25 degrees C. This is the industry standard for all photovoltaic panel ratings. However, it is the “best case” scenario.
There’s also energy company advocate and writer Al Weinrub. He argues that decentralized energy, or putting renewable systems in as many places in a community as possible, generates wealth, spurs economic revitalization and helps adapt to climate change.
hydropower is very safe. People get scared by it because a little knowledge can be a dangerous thing; they find out that hydrogen is involved and they freak out. That’s a bit premature. In hydropower, the combustible gas is extracted only as needed and is burned steadily from the water, unlike in other technologies where larger amounts of combustible gases are burned.
One of the renewable energy sources that is really moving forward is known as biomass. This allows for common waste materials including wood, trash, crops, and even gases from landfills to be used to create energy. This is also going to reduce the amount of materials lying around in our landfills. Maybe one day the use of geothermal energy will be more plausible. Right now though it is complex, complicated, and expensive. The procedure for accessing it involves going into the core of the Earth more than 4,000 miles beneath the surface.
Building solar panels is not as difficult as you might think. The solar cells are what transform sunlight into energy. These cells are wired together. Once this transformation has taken place, heat light and hot water are available literally on tap. Your appliances can also be powered up to work for you in this way. The materials will set you back in the region of two hundred dollars. Do it yourself stores and most hardware stores will stock these items.
California’s Global Warming Solutions Act sets a rather lofty target of the state getting a third of its energy from renewables by 2020. The law has spurred growth in renewable power production and facilities construction. However, if the trend of corporate green power purchases continues, that goal may indeed be reachable.
