Personal Footprint
You can take steps to address your carbon emissions right now.
First you need to calculate the emissions you release from driving your car, your air travel, and the electricity you use in your home.
We'll then calculate how many carbon credits you need to offset your emissions. Our safe online payment process makes it easy for you to make a difference in just a few clicks.
You can also use the calculators to measure and offset flights, car trips and electricity associated with an event, such as a birthday or wedding celebration or honeymoon.
When you buy carbon credits through Climate Friendly, you're in effect putting renewable energy back into the power grid to replace the energy from fossil fuels that you have used.
Most of us do our best to address global warming by switching off lights and appliances, reducing our waste and walking or cycling more. But the global average emissions for an individual remains 5 tonnes a year, rising to 28 tonnes in countries such as the US and Australia.
Climate Friendly helps you to take immediate and meaningful action against global warming - contributing to an effective, long-term solution.
20 tips for energy saving
You don't need to be a Climate Friendly customer to reduce your carbon emissions. Here's 20 tips to get you started.
Buy renewable energy. Make the switch to save around 30% of your household greenhouse gas emissions a year.
Drive less. Cars contribute to a high percentage of the world's carbon dioxide emissions. Before getting into your car, think about walking, riding your bike or taking public transport instead. It's better for your health and the planet.
Turn off lights and switch your bulbs. Turning off the lights when you leave a room or office and switching to compact fluorescent bulbs can make a big difference to reducing greenhouse gas emissions. And it saves you money in energy costs.
Insulate your home and body. Look for ways to keep warm in winter without heating. Insulate ceilings, walls and your hot water heater, and wear a coat instead of turning up the heat.
Open the window, turn off the air conditioning. Air-conditioning is a great contributor to greenhouse gas emissions. In summer, open your window, use a fan instead of air-conditioning, and always turn off air-conditioning when not at home.
Switch off standby. As much as 10% of your home's emissions may be from appliances like computers, televisions and other home entertainment devices left on standby. Try to always turn off appliances at the source.
Conserve water. Use less water when possible. Install a rainwater tank or even a grey water system that channels water from showers and baths to toilet and garden systems.
Fly less. Take international trips sparingly and make the most of local destinations. Do business remotely via conferencing units or online conferencing applications. This will mean fewer flights, less travel time and savings of up to 10 tonnes of emissions per international trip. If you need to fly, consider offsetting your flight emissions.
Use alternatives to electricity. Switching to solar hot water or gas heating can save as much as 3 tonnes of greenhouse gas emissions per year.
Buy efficiency. When buying high energy-using equipment or appliances such as refrigerators, washing machines and dishwashers, try to choose the item with the best energy rating.
Dry washing outside. One t-shirt can send 4 kg of carbon dioxide into the atmosphere during its lifetime, mostly due to washing and drying. Whenever possible, use the power of the sun or a clothes horse instead of the dryer.
Choose a hybrid, biodiesel or fuel-efficient car. When buying your next car, make the move to a greener vehicle. It can save up to 3 tonnes of greenhouse gas emissions a year.
Work from home. Even one day a month working from home can make a difference by reducing transport emissions. Ask your boss if you can work from home occasionally and skip the commute.
Pay bills online. Paying your bills online saves paper, transport energy and time.
Own just one refrigerator. Old, inefficient second refrigerators and freezers are huge energy users and often have other environmental issues such as leaking chemicals that damage the ozone layer. If you don't really need it, look into local buy-back schemes or dispose of old refrigerators and freezers properly to ensure ozone-depleting chemicals are not released into the atmosphere.
Eat lower on the food chain. Producing meat uses a lot of energy and water and often requires pesticides and other chemicals. In fact, producing meat generates about 18% of global greenhouse gas emissions. Eating less meat is good for you and the environment.
Buy local. Buy food and other products that are grown and produced locally to reduce emissions from transportation and to support your local community.
Green your event. If you are holding a conference, family reunion or wedding, do what you can to reduce the environmental impact by buying locally, choosing energy-efficient and environmentally aware venues, and offsetting remaining emissions.
Buy recycled and 'vintage'. Buying used or recycled goods avoids the energy used and emissions released in making a new product. Always try to recycle your waste and unwanted goods.
Check your tires. Inflating your car's tyres to their proper level means the car runs more efficiently, uses less energy and produces fewer harmful emissions

A Funding Roadblock Ahead for Clean Energy
By KATE GALBRAITH
NEW YORK — A landmark climate bill that narrowly passed the U.S. House of Representatives on Friday would cap greenhouse gas emissions across the United States for the first time and also create a national target for renewable energy production.
Environmentalists and advocates of clean energy hailed the news in a flurry of statements. Frances Beinecke, president of the Natural Resources Defense Council, called it a “dramatic breakthrough for America’s future.” Denise Bode, executive director of the American Wind Energy Association, described the renewable energy target as “a key first step in balancing our electric generation mix.”
The legislation, however, remains far from becoming law. The House passed the bill only narrowly — and it has been weakened since being introduced months ago — and the fight in the Senate may be even tougher.
In the meantime, there is also the pressing matter of financing renewable energy projects. Since the economic crisis began last autumn, the once red-hot activity by wind and solar developers has slowed sharply. The U.S. government’s stimulus package is supposed to help (although some portions of its aid for renewable energy have not yet been disbursed).
But many advocates of renewable energy are thinking longer term. What happens when the stimulus funding runs out, as it is scheduled to do for the industry’s projects in the next year or two?
“One of my big fears is that we will fall off a cliff,” the director of climate change and energy initiatives at Google, Dan W. Reicher, said in an interview in New York last week.
Lowell Ungar, the policy director for the Alliance to Save Energy, an efficiency advocacy group, echoed the sentiment. “The concern is that you spend billions of dollars building up this industry, training people and creating new jobs and new companies, and it all disappears,” he said.
Perhaps because of its relative newness and small size, the renewable energy industry has been hobbled by a history of uncertain funding.
In the United States, a tax credit to aid wind energy has threatened to expire about every year or two over the past decade, causing the industry to complain that long-term planning is impossible. Congress has repeatedly extended the credit on a short-term basis, but manufacturers of wind turbines have hesitated to establish plants in the United States for fear that the demand for their product might evaporate. (The three-year extension provided in the stimulus package has given a measure of stability, although it arrived — as per the definition of stimulus — just as private investors had pulled back.)
Solar energy in Spain is another classic example of roller-coaster funding. There, the government provided a strong feed-in tariff — a high payment to producers of renewable energy — and solar companies rushed into the country. Last autumn, however, the government decided that the explosive growth was costing too much and capped the amount of solar power that could qualify for the incentive.
“By having something that kind of shot out through the roof and fell back to earth, that shocked the system,” said Julie Blunden, the vice president for public policy and corporate communications at SunPower, a major solar manufacturer. “The boom and bust was very disruptive to building a base of business in Spain.”
Greece and the Canadian province of Ontario have also had yo-yo policies on encouraging solar power, Ms. Blunden said, though she added that both governments were trying to address the problem.
In the United States, the industry is planning for the period after the stimulus package, to avoid a falloff.
“There is already discussion in the market about ‘what comes next’ when the stimulus spending has run its course,” the head of the renewable energy group at the law firm Alston & Bird, Tom Amis, said in an e-mail message.
“Given the volatility of fossil fuel prices (natural gas, the key marginal price driver, has recently been at record lows), and the continued need for a long-term manufacturing increase to achieve the necessary economies of scale, there is a consensus in the industry that there needs to be a ‘second act.”’
Should the climate legislation passed in the House become law, it could lead to one type of solution. The cap-and-trade provisions would effectively raise the price of generating electricity using fossil fuels. This would help clean energy technologies — which are expensive relative to coal and natural gas — to become more competitive.
Because a cap-and-trade system, depending on its final structure, would also be likely to auction off some allowances to pollute, it would create a revenue stream that could be plowed back into energy efficiency and the renewable energy industry.
The auction provisions in the climate bill are weaker than many environmentalists had hoped, however. There would also be relatively few allowances auctioned off in the early years of the legislation, which would take effect in 2012 if passed — leaving a gap after the stimulus funds run out. Mr. Ungar of the Alliance to Save Energy suggests a mechanism that would let state governments borrow in advance against expected future revenues from the climate bill’s allowance provisions and use that money to maintain smooth funding for energy efficiency and renewable energy.
Another solution, pushed by Mr. Reicher and others, would establish a government-backed clean energy bank, modeled on the Export-Import Bank and the Overseas Private Investment Corp.
Such a funding apparatus, which is under consideration in various forms in Congress, could be loosely affiliated with the Department of Energy and provide aid like loan guarantees and direct loans designed to help the small renewable energy industry to scale up. Such a bank could continue some of the renewable funding measures in the stimulus package. It would also extract clean energy policies from the bureaucracy of the Department of Energy, which has complicated the release of some stimulus funds.
To be sure, the ultimate hope is that the renewable energy industry can stand on its own, without permanently relying on the government for financing. As the stimulus provisions expire, the industry hopes that the banks will be back on their feet and able to finance projects. From the companies’ perspective, standing on their own would have the benefit of avoiding the risks and uncertainties that accompany sometimes-fickle government policy.
But as the industry works up to a meaningful scale from tiny and often experimental technologies, renewable energy developers will be happy to take the help.

Energy Management Green energy
Here is an example of a client who as part of there renovation installed solar geysers for the bedrooms, guest rooms and servants quarters. This renovation made it easy to position the geysers optimally and to get the thermal collectors in the best position possible.
The house presented us with a large surface area, ideal for Solar collection. North facing roof is ideal!
Large Double story house with high pitched roof means scaffolding has to be used. Collectors need to be properly positioned for maximum benifit.
Geysers are positioned above the collectors on the inside of the roof. This allow for the hot water created on the collector outside to rise naturally into the geyser, where it is stored for use within the house.
A vey neat and attaractive result is left on the renovated house, plust they are saving massive amounts on there energy usage

Bonus: World’s Largest Landfill Gas Recuperation PlantPuente Hills in Whittier, Calif.
Producing power from the gas that seeps out of landfills is a better alternative than simply flaring it. (Though it’s debatable whether or not landfill gas constitutes a renewable resource, because yields of combustible gas from landfills decline between 2 and 15 percent per year after a landfill is capped and no more garbage is being added, according to Jeff Pierce, vice president of power plant development company SCS energy). Landfill gas is about half methane and half carbon dioxide and also contains water vapor, which makes it more difficult to handle than conventional natural gas.
The world’s largest landfill gas plant sits atop the Puente Hills landfill—the largest in the U.S.—which accepts trash from Los Angeles County. Pierce says that because this active landfill is still growing, production at the 20 year old Puente Hills landfill gas plant has not yet peaked, and averages about 50 megawatts.
Another 50-megawatt landfill gas plant sits atop another gigantic dump in Incheon, South Korea. Currently there are no plans for units larger than either the Puente Hills or Incheon facilities.

Lighting Control
Retrofitting standard metal halide hi-bay fixtures to fluorescent hi-bay fixtures can generate energy cost savings of about 50 percent. How does reducing the resulting energy consumption by another 30+ percent sound—made possible by switching to fluorescent?
While tapping what remains arguably the hottest lighting retrofit market, distributors should understand the full advantages of fluorescent over probe-start metal halide, such instant-on and re-strike, which enables the use of switching strategies typically not practical with HID light sources.
Example: An occupancy sensor installed in each fixture senses a lack of occupancy in the area, or a photosensor senses high light levels due to daylight contribution, and either switches off the fixture or its outboard lamp. This provides a choice of energy savings and, if desired, flexible selection of light levels.
An additional 30-80 percent energy savings using occupancy sensors and 10-30 percent savings using daylighting controls can be achieved in a hi-bay fluorescent upgrade, says John Ireland, OEM channel manager for Watt Stopper/Legrand.
Mike Connolly, market development manager for Lithonia Lighting - Industrial Products, says inboard/outboard switching—achieved by separating circuiting ballasts within the same fixture, enabling 0/50/100 percent and 0/33/66/100 percent lamp output/power—is an inexpensive way to gain the benefits of flexibility from the lighting system. “For example, in a gym, light levels can be lowered for school productions or other needs outside of athletics,” he says. “Multi-lamp fluorescent fixtures offer many light level possibilities for user control, daylight harvesting and other applications.”
Occupancy sensing is the predominant strategy, particularly in applications such as distribution centers, warehouses and bulk storage areas. “Any area of 50 percent or less usage levels will accelerate the project’s payback period—even with relatively modest electric rates of $0.07 per kWh,” says Connolly. To optimize lamp life, particularly when the fixtures have high switching activity—more than six on/off cycles per day—programmed-start ballasts and a minimum 15-minute sensor time delay are recommended.
Passive-infrared (PIR) technology is standard in occupancy sensors used in hi-bay applications. “Besides its low cost, most spaces in hi-bay applications are within the line of sight of the sensor, large motion is usually being detected, and little adjustment is required after installation,” says Tom Leonard, director, marketing and product management for Leviton Lighting Management Systems. In hi-bay applications, the sensor may have a lens that provides 360-degree coverage for open areas or a narrow linear coverage for warehouse aisles

Reduce Energy consumption
Priority Energy lights a regional award winning tennis complex
Date Announced: 05 May 2009
Hillcrest Racquet Club is one of the top tennis facilities in the North Eastern United States being awarded the club of the year 2008 by the USTA Middle States, operating in Reading, Pennsylvania. Hillcrest Racquet Club was looking to find a lighting solution to reduce their monthly demand for lighting while improving the light output for the tennis courts and the general area. The project has completed the first phase of the general area using the U-tube replacement, 4ft replacement, PAR 30 and the medium Incandescent replacement LED lights of Priority Energy. The second phase of the project will be to convert the court lighting from the 1,000W Metal Halides. The major concern of the tennis club was to ensure the best color of light as well as to have sufficient light output throughout the large 10 court facility. Priority Energy installation was to replace 4 fluorescent products with 3 of the 15W LED products achieving higher light output and the track lighting for the Pro Shop. "Hillcrest Racquet Club are thrilled with their new lights knowing that they have been one of the first sports facilities to have a higher quality light while reducing their huge monthly operational costs of their lighting which represent 80% of their electrical bill." said Paul Prior CEO of Priority Energy. Hillcrest Racquet Club have not only reduced their monthly electricity bill already by $500 per month but have also reduced their carbon footprint by 760 MT. "We expect that with the completion of phase 2, Hillcrest Racquet Club will see a 65% reduction in their electrical bill each month." added Mr. Prior.
