Energy Efficient Roofing

Hot roofs absorb heat, causing air conditioner systems to work harder to cool during the warmer months of the year.

A cool roof uses material that is designed to reflect more sunlight and absorb less heat than a standard roof. Cool roofs can be made of a highly reflective type of paint, a sheet covering, or highly reflective tiles or shingles. Cool Roofs can lower the temperature of your roof by up to 50 degrees, which will reduce cooling costs.

Water Saving Tips

 

water-conservation1

Fix leaks.  The most common fixture that leaks is the toilet flapper.  Checking for leaks should be part of your overall maintenance plan and should be done on a regular basis. Perform a water audit. Take a look at your water meter when no one is likely to be using water.  If the meter is moving, you have a leak.

Install water-saving devices. Can you transform your single flush toilets to dual flush with a kit?  How about installing a Smart Faucet in every bathroom?  The EPA has rolled a complete line of water saving fixtures under its WaterSense label, however, but these are merely minimums.  Individuals should go beyond the minimum by installing 1.5 gallons per minute (gpm) shower heads when the WaterSense minimum allows shower heads with flow rates of 2.5gpm.  Rebates may also be available from your local utility to promote the installation of new high efficiency toilets that utilize 1.28 gallons per flush or better.

Upgrade to water saving appliances. Old dishwashers and top-loading washing machines are incredible inefficient, utilizing as much as 25 gallons per load of dishes and 35 gallons of water per load of laundry.  New high-efficiency models utilize a fraction of the water. Dishwashers in the two gallon range are very effective and front-loading washing machines use about a third of the water of what top-loaders use and rebates may be available.  The less water an appliance uses, the less electricity and natural gas that will be needed to heat that water.

Rethink landscaping. Plant what’s appropriate for your region and you will reduce water consumption, increase habitat for native species and raise the value of your property.  Re-landscaping is a big expense, but you are paying to water and maintain plants every year, year and year out, when you could be pocketing the money you currently budget for water.

Caulking Tips

Caulking seems like a relatively easy thing to do, and in most cases it is. There are simple tips and tricks that can make a big difference between a easy, seamless, hassle-free caulking job and one that’s messy and full of frustration. Before you start your next caulking job, here are a few things to keep in mind.

Window-Caulking

  • Purchase a good-quality pro-style caulking gun ($10). Skip the cheap low-end guns that utilize a ratcheting plunger. Ratcheting guns don’t operate smoothly, making it hard to apply a clean, uniform bead.
  • Use blue painter’s tape to protect your windows and the other side of the joint you are trying to fill. Leave a gap between the tape about 3/8ths of an inch wide.
  • Find a utility knife as when you cut off the top of the caulk tube, you do not want an uneven or straight cut. Make the cut at a 45 degree angle.
  • When you apply the caulk you will hold the caulk gun at approximately 45 degree angle.
  • Bend a piece of cardboard and practice on the seam before you attack your first seam. You could start in a less visible area where any mistakes will be less noticeable.
  • After you apply the caulk, use a plastic spoon to smooth the seam so that it is more or less flush.
  • Keep the tip of your caulking tube clean and free of dried caulk.
  • Make sure you pull the tape off before the caulk dries to leave clean seam.

Proper caulking and sealing will lead to an increase in energy efficiency of a home’s heating and cooling systems. Caulking can also substantially extend the life of windows and doors.

Conservation Tip: Maintain Your Water Heater

Water heating currently represents up to 20 percent of US residential energy consumption, making it the third largest energy consumer in homes, behind heating and cooling and kitchen appliances.

Maintaining your water heater will not only save energy, but also will extend the life of the water heater. Here are a few tips to maintain your water heater and save up to 200 lbs. of CO2 per year:

  1. Drain water heater annually. Sediment collects at the bottom of the tank, which leads the hot water heater to perform inefficiently and lead to higher energy costs. By draining the water heater once per year, you will eliminate the build up inside the water heater and keep the water heater working efficiently.
  2. During the annual draining process, Inspect the water heater for damage and assess system performance. Check for leaks and any strange noises, may be a sign that it is time to replace your water heater.
  3. Set water heater temperature. Manufacturers typically preset new hot water heaters at 140 degrees Fahrenheit (60 degrees Celsius). The U.S. Department of Energy (DOE) recommends homeowners set the heater at 120 degrees Fahrenheit (49 degrees Celsius) to save money and energy. For each 10ºF reduction in water temperature, you can save between 3%-5% in energy costs.
  4. Insulate water heater. Heat loss from the tank and pipes causes decreased energy efficiency in a conventional hot water heater. You can save money by purchasing a water heater blanket from your local hardware store.

Why Teach Fuel Cells?

Renewable technology now plays an important role in the modern science classroom, introducing children to the astonishing potential of alternative sources of energy. However, while most children have heard of solar panels or wind turbines, fuel cell technology still remains a mystery to many. Yet this is a crucial time, with the mass production of hybrid fuel cell vehicles, the construction of hydrogen refueling infrastructure in the EU and America and international telecom companies increasingly turning to fuel cells for their energy needs. Fuel cells have an enormous amount to teach, both in terms of key scientific principals and their relevance to the greentech innovations happening all around us.

Hydrogen fuel cells

Fuel cells are bursting with fascinating science! The key process of a hydrogen fuel cell is the conversion of hydrogen atoms into electrical energy by separating the nucleus from the electron. The electrons are then diverted around an electric circuit while the positively charged hydrogen ions travel through the proton exchange membrane. Then there’s the generation of hydrogen itself—the separation of hydrogen from oxygen through water electrolysis, the hydrogen molecules with a slight positive charge travelling to the cathode while the slightly negatively charge oxygen is attracted to the anode. Molecular bonding, valancy, ions, electrolytes and so much more, just from one alternative technology.

Other types of cell

While hydrogen dominates the headlines at the moment, other fuel cells have enormous educational potential. Direct ethanol fuel cells are in many ways the most efficient power generators of the Horizon education range. The process lasts for hours, does not require combustion, and is completely silent. Saltwater fuel cells operate a little differently, generating electricity through a saltwater electrolyte with magnesium plates around the anode.  Thermal cells convert the temperature difference between hot and cold water into electrical energy. One of the key lessons of these alternative fuel cells is just how vast and varied the science is—and how many options we would have if we truly embraced a fuel cell economy.

Sustainability

With most of our education kits we try to integrate more varieties of alternative technology to enable students to build self-sustaining renewable energy systems. Wind turbines or photo voltaic panels power the electrolyzer to separate out hydrogen from water. The fuel cell converts hydrogen to electrical energy which then powers a propeller or LED— a great way to demonstrate the principles of energy conservation and conversion. Also, students also get to study things like the effect of shade on solar panels, wind resistance, the optimum number of blades for effective wind energy generation and many other tests and experiments.

Universal Ideas

The addition of fuel cell and renewable technology to the science curriculum doesn’t mean that the basics principles of physics and chemistry are somehow overlooked. In fact our fuel cell education sets reveal the workings of water electrolysis, the electrical circuit, resistance, voltage, current, RPM and everything else a conventional lithium battery electrochemistry svet can supply. Plus, extra features such as the Renewable Energy Monitor allow teachers and students to not only measure energy, but also take this data and view it graphically in real time on a computer screen.

Fuel cells are the future of emergency backup power, transportation, aerospace, telecommunication support and so much more. With a carbon-neutral world fast approaching, it’s time we introduced students to this crucial technology and started inspiring the next generation of scientists to push the boundaries of renewable science.

Benefits of Using Dryer Vent Seal

Reasons to Install Dryer Vent Cover

Have you ever noticed that the room containing your clothes dryer is usually the coldest room in your house? Most clothes dryers are connected to a 4″ diameter exhaust duct that runs directly to an opening on the exterior of the home. During the winter months, cold air leaks in through the duct, through your dryer and into your house, allowing your heated air to Imageescape.  In addition to the energy loss issues, other problems include insects, mice and other pests to enter through the exterior vent.

One solution to the problem is to install a Dryer Vent Seal Cover. The installation of the dryer vent vent kits with a floating cap design can provide several benefits in the following areas:

Energy Efficient

Because dryer vent cap only opens when the dryer is in use, the movement of air, either air conditioned to the outside, or cold exterior air to the inside. This design also keeps rain, snow and dust or other debris from blowing into the dryer vent. Because cold air isn’t allowed in and heated or cooled air isn’t allowed out, this will improve the energy efficiency of maintaining air in the effected area.

Fire Safety

The louvered design of the dryer vent seal allows lint to pass freely to the outside, preventing the buildup of lint in the dryer vent. Collected lint is very flammable and the use of wire mesh or screens by many homeowners traps the lint and increases the collection of the flammable material.
