Have you wandered the aisles of your local home improvement store trying to determine what you need for your home’s air conditioning or furnace? If you are unsure about what is wrong with your equipment, get a professional’s opinion or you could be spending money unnecessarily.
Sewage and industrial sludge is being managed as a liability. Current outdated regulations and technologies focus on the least-expensive means of the sludge disposal. Sludge management needs to be redirected toward the recovery of energy and chemicals embedded in the sludge and guided by the principals based on the current scientific findings and technology. Environmental and demographic considerations need to play an important role in this new approach geared toward sustainable and energy-efficient waste management practices.
This past year has been a hallmark year for the advancement of Light Straw-Clay building. The publication of our new book The EcoNest Home and the latest edition of Franz Volhard’s book Light Earth Building translated into English, and the inclusion of Light Straw-Clay Building in the International Residential Code has made this beautiful form of construction accessible to more people than ever before in modern times.
As the energy industry evolves, so does big data. Big data is probably best known for tracking people’s behaviors, purchases and viewpoints, but it can have many other applications. Now the energy sector is tapping into the resources big data has to offer. From renewable energy to oil, gas and coal, this data science can help many companies maximize profits, reduce costs and even lower risk.
A seemingly simple, light-trapping prism could revolutionize the future of solar power. The glass prism, which maximizes the amount of energy it can derive from sunlight, contains a 28-square centimeter, four-junction miniature module that works by utilizing a hybrid receiver designed to convert electricity from each sunbeam more than other devices.
Choosing the right size solar photovoltaic system for your home depends on where you live, how much electricity you use, the specifications of your roof, as well as the policies in place at the state, municipal and utility level. By optimizing your system, you can make the most of your solar investment.

If you fall asleep or can't think straight at holiday gatherings, don't blame it on the turkey (or your relatives)! Research indicates that carbon dioxide is not only a greenhouse gas, but elevated levels of it are detrimental to human health and cognition. Learn how improving your indoor air quality will increase your health and stamina during holidays.
There are five main areas of the home responsible for wasting the most energy. At the top of that list is windows, and one of the most effective ways to decrease your home’s carbon footprint is by replacing old, drafty windows with new, air-tight Energy Star-qualified windows.
The U.S. Department of Energy estimates that the amount of energy lost annually through windows costs consumers $35 billion. Heat loss and heat gain through and around windows accounts for between 10 and 25 percent of our heating and air conditioning usage, the largest consumer of energy in a modern home. Here are some ways to make sure your windows are as energy-efficient as possible.
When your electronics say “low battery,” it means just that: The batteries are low but not dead. The energy that remains in seemingly dead batteries can be used in this simple night light project that you can build at home in about one hour. Your new night light will shine for months and is reusable for years, powered by “dead” batteries.
The third in a series of weekly postings about my visit to Cuba with a delegation of energy industry professionals, and a Cuban colleague’s visit to Vermont where I developed a similar tour. Along the way we learned about efficiency and renewables, and some striking contrasts between ourselves and our countries were revealed.

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.
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.
If someone told you that you were losing money just by sitting in your home, you would probably want to do whatever you could to change that. Well the reality is that your home is using up energy regularly, and there is a huge chunk of that energy that you do not even need. Luckily, we live in a time when technology is constantly coming up with ways to fix problems such as these. Here are some of the ways that technology can help to save the environment, as well as your wallet.
Upgrading wall insulation is tricky. You can't see the insulation that is (or isn't) in your walls, and it's not easy to install new insulation in a hidden wall cavity. One solution that shows promise is filling wall cavities with injections foam.
Let's face it: Tax audits have given the word "audit" a bad name. But a home energy audit is a good thing, and every home can benefit from the information and recommendations a home energy audit provides.
The work invovlve in tranforming a house that wastes energy into a house that's 50%-95% more energy efficient is called a "deep energy retrofit." We need to find ways to do more of these to save energy, money and the environment.
We know that heating, cooling and operating our buildings is responsible for 40 percent of total energy expenditures in this country. That’s a huge percentage. But we also know how to test, evaluate and improve buildings so that energy use can be cut dramatically.
There are many ways that each of us can lessen our unhealthy dependence on filthy fuels. You can do so in every area of your life, from choices you make regarding your house and home improvements, to food, transportation, and other consumer choices.
