There are a number of ways to make your home more energy-efficient. These methods are practical and cost-effective. The bottom line is that they will save you money with heating, cooling and supplying electricity to your lights and appliances.

Solar Panels For Your Home

One solution is add solar panels to your home. These can used to supply electricity and also can be used to help creating hot water in your potable water supply.

Solar panels absorb sunlight using photovoltaic cells. These photovoltaic cells create direct current, which is type of electricity that flows in one direction. However the appliances used in your home use alternating current, which is a type of electricity the runs in two different directions through the wiring of your home in phase system. Your solar panel system will therefore need an inverter to convert the DC electrical energy into usable AC electrical energy.

Most home owners install these panels on their roofs. However this is not say you cannot setup a row of these panels in your backyard where the most hours of sunlight hit the ground.

Building solar panel with proven plans would be a practical solution helping to reduce energy costs and make your home more energy-efficient. However this will be technical task and proper guidance will be necessary for most individuals.

Roof Top Solar Panels

Home are being constructed with roof tiles that have solar panels built-in them. These roof tiles look like a normal roof but solar panel are built into them and will help subsidize your energy bill.

Windows as Solar Panels

Recently the solar power industry have found methods to use windows to provide energy for a building. These solar-powered windows can be used to replace the existing windows in a building and make the structure more energy-efficient. These windows contain tiny solar cells that convert sunlight into energy. This energy is converted into electrical energy and can used directly. Excess electrical energy is stored in a battery to used later.. Apparently one of these windows can supply enough energy to charge a cell phone twice a day.

Other Energy Conservation Methods

Using energy-efficient light bulbs is one way to make you household more energy-efficient. There are a number of energy-efficient light bulbs available to the consumer. These include the halogen incandescents, compact fluorescent lamps and light emitting diodes (LEDs). These are very popular and can be purchased in various hardware and grocery stores.

Energy inefficient incandescent light bulbs are being phased out but are still available at lower cost per unit. However they have a shorter life span when compared to these more efficient sources of light. You do the math.

Would you like to reduce electrical costs related to your compressed air system? More than likely – you can. Start by determining your annual compressed air electrical costs by using this formula:

Brake Horse Power X 0.746 X Annual Hours of Operation X KWH (Kilowatt-Hour) Cost (divided by) Motor Efficiency

NOTE: 1 CFM (Cubit Feet per Minute) @ 100 PSIG (pound-force per square inch gauge) FOR 8760 HOURS COST $110.00 PER YEAR IN ELECTRICAL COST

Next…follow these Top 7 Compressed Air Energy Saving Tips:

1. Fix your Air Leaks

If you do nothing else – follow this one tip: Find and fix your compressed air leaks. Air leaks are industrys’ “biggest looser”!

The average plant loses 20% to 30% it its compressed air through multiple small air leaks. The money spent on man power and parts to find and fix these leaks is well worth it. Note (a 1/4 inch hole will flow 103 cfm @ 100 psig)

2. Change to Synthetic Lubricants

If you are using petroleum based lubricants, you could experience up to an 8% energy savings by switching to Compressor Synthetic Lubricants. Plus extend equipment life and save on oil changes and disposal cost.

3. Reduce Plant Operating Pressure

If possible – reduce overall plant pressure. Less pressure > Less CFM used > less energy consumed.

TIP: Reduce plant pressure 2 pounds at a time, then test run for minimum 24 hours. If any equipment has issues…then increase pressure 2 pounds until running smoothly again. For every 2 pound pressure reduction -you save 1% of the electrical cost to run the air compressor.

4. Check Differential Pressure on Air Compressor Filters.

Start at the compressor cabinet filter then check the compressor inlet filter.

Note: A dirty inlet filter can cost you 1% to 3 % in additional electrical costs. Why? Because decreased air flow to the compressor inlet valve increases the compression ratios resulting in more run time.

Next check the air/oil separator differential pressure under a full load. A new separator causes a differential pressure drop of approximately 2-3 psig. When your pressure drop reaches 8-10 psig, then it is time to change your separator elements. A dirty separator element can cost you up to 5% in additional electrical cost.

Next change the control air filter element. This often over looked, but still important filter where the controls receive their air signal. A pressure drop here causes the controls to receive the lower pressure signal loading the compressor more and using more electricity.

5. Reduce the Compressor Inlet Temperature

By reducing inlet air temperature 10°F below 70°F, you save 2% on electrical usage. Your benefit increases up to 8% on a 30°F degree day. But increasing the inlet temperature 10°F above 70°F will cost you 2% in additional electrical usage for every 10°F up to 10% at 120°F. (Inlet temperature has very little affect on Lubricated screw compressors)

6. Check Differential Pressure on Compressed Air Line Filters.

Size Compressed Air Filters to be twice (2x) your compressor CFM flow rate. This will lower your pressure drop approximately 2-3 psig and save 1% on energy costs. Elements will last twice (2x) as long and you will save on maintenance costs.

7. Know what quality of compressed air your plant needs.

The cleaner & dryer the compressed air the more energy used.

Check with the manufacturer of your equipment to determine the quality of air needed.
