The sun provides us with enough clean energy that if ever effectively harnessed, we might never need any other form again. Sadly, we are only able to harness a fraction of it's potential. Fortunately, we are making great progress to get where we want to be.
Mankind’s use of fossil fuels during the last 200 years has dumped millions of years of sequestered carbon into the atmosphere in the form of Carbon Dioxide. Since the beginning of the industrial revolution, 315 gigatons of carbon have been added to the atmosphere, leaving the carbon cycle 315 gigatons out of balance.
Never in the history of the world has there been such a high-ranking member of society to advocate passive solar design than Socrates. He felt so strongly for building with the sun in mind that he even set up a class to teach his acolytes how the finer points of putting up a passive solar house.
Renewable energy is often seen as a way to have it all and still feel “green” and it is indeed at a glance more environment friendly than conventional power, but no power has as low footprint as the power not used.
On sunny days it delivers about a half a megawatt of electricity to the biodiesel plant, while providing strategic shade to plants below. Energy is produced above as farmers harvest below in a genuine double cropping scenario.
Having a properly maintained water heater is like going to the dentist: No one wants to do it, but it’s gotta be done. Ideally, you should have an inspection and necessary maintenance performed on your water heater once a year.
It might seem like a small thing, but your refrigerator can be a HUGE drain on your energy bill. We’ve already shown you how to check for leaks in your refrigerator seal—now let’s take the next step in keeping your fridge in top working order.
Attics can be a huge energy drain if they are not insulated sufficiently. We’ll leave the
heavy lifting for next weekend, but for now look for uneven insulation, base sports, water damage, and anything else that looks out of place.
It’s springtime and the weather is getting warm, but that is no excuse for letting money and energy fly out the window every single day. Hopefully you were able to find all the drafts and leaks in your windows last fall (if not, now is just as good a time as any).
Did you know that heat transfer through windows can account for up to 25 percent of your energy bill by allowing heat out during the winter, and makes your air conditioner work overtime to combat the sun’s warming? Drafts and leaks can be the biggest culprit of energy waste but can also be fixed with relatively little effort.
More than the electricity needed to run these machines, the “rinse hold” hot water setting that many households use is the biggest energy drain associated with dishwashers – as much as 80 percent of the energy your dishwasher uses goes to heat water.
To me, the most important features of a sustainable building are not its technological wonders but its simple design features: common-sense strategies that should be incorporated whether the building becomes LEED certified, Energy Star certified, or is just trying to be environmentally friendly.
There are two situations which do not require you to be heating your home: when it is warm and when you are not at home. Since it is still a bit chilly outside, you may want to consider setting up a routine of turning down the set temperature on your thermostat when you head out in the morning and when you go to bed.
Some large electronics can use as much energy as a light bulb while in "stanby" mode, meaning you should unplug them when you leave the house or know you won’t use them for awhile. Having a large electronic setup plugged into a power strip makes it much easier to completely power it down, especially if it has a lot of plugs like a home theater system or computer.
CFLs use 75 percent less energy and last 10 times longer than an incandescent bulb. I know that when I purchased new lamps for my house, they had a whole shelf of incandescent bulbs right next to it, and I had to go search the store for CFLs, so I understand if you are currently using incandescent bulbs. But it’s worth the switch — not only are CFLs equal in light quality, they last way longer and will save you hundreds of dollars over their lifetime.
Tonight when you get home from work or school, call your utility company and ask what incentives they have for you to get an energy audit for your home. Many utilities have been offering free energy audits for years, but very few people have actually taken advantage.
Defying conventional wisdom about the limits of wind power, in 2012 both Iowa and South Dakota generated close to one quarter of their electricity from wind farms. Wind power accounted for at least 10 percent of electricity generation in seven other states. Across the United States, wind power continues to strengthen its case as a serious energy source.
