Cool Roofs Save Energy & Money, Help Fight Climate Change

Having a “cool” roof is pretty hip – but that’s not only what “cool” means in this case! Cool roofing refers to the use of thermal roof coatings that reflect sunlight away from the house, rather than absorb it, as a way to moderate building temperatures and reduce the amount of energy needed for home heating. In this era of increasing energy costs and growing concerns about the environmental impacts of burning fossil fuels, cool roofs – known as thermally coated roofs in the UK -  make sense because they save energy and money and help slow climate change. Here is more information on cool roofs, thanks to Improve a Roof, our sponsors for this post.

 What difference does a roof make?

Any surface exposed to solar energy will get hot. Traditional roofing materials absorb 85 to 95 percent of the solar energy that reaches them, increasing the temperature of the rooms below. Thermally coated roofs reflect more of that energy back out into the atmosphere.

Benefits

A cool roof offers several important benefits. Because it transfers less heat to the building below, the building requires less energy for cooling, a big advantage in the summer when many homeowners max out their air conditioning – and their electricity bills. By some estimates, a thermally coated roof can reduce a homeowner’s electricity demand by 14 to 38 percent (depending also on how well the roof and home are insulated, among other factors).

Most electricity is generated by coal-fired power plants. Burning coal creates air pollution and carbon dioxide that causes climate change. Because cool roofs reduce electricity demand, they also help keep the air clean and help minimize climate change.

Plus, cool roofs can increase comfort for the people living in them, especially in homes that do not have air conditioning. In the picture above, the bottom photo shows how much energy (heat) is being absorbed on an untreated roof, compared to the top photo of the same roof that's been thermally coated.

Brand new, or retrofit?

Cool roofs can be installed on new construction, but homeowners can also retrofit their existing roofs by working with a contractor to apply coatings or membranes.

What is a cool roof made of?

There are generally two types of roofs –low-sloped, and steep slopped.  A low-sloped roof is mostly flat, with only enough incline to provide drainage; it’s normally used on commercial, industrial, warehouse, office, retail and multi-family buildings. Most homes have a more steeply sloped roof. The kind of roof usually determines what materials can be used to make it cool.  Contractors can use surface treatments like thermal coatings that reflect the sun’s rays, restrict the growth of algae, and are waterproof.  They can also apply membranes, pre-fabricated sheets applied in a single layer (these are better for a flat or low-sloped roof).

What will it cost?

If you’re interested in making your roof cool, get bids from contractors like Improve a Roof who can also tell you what thermal roof coatings are appropriate for your home. Don’t forget to factor into the cost the amount of money you will save on cooling your home in the summer. Some communities may provide tax credits for installing energy-saving technology, which will add to the savings.

Consumer Choice in Electricity: An Easy Way to Reduce Your Carbon Footprint

I live in Maryland, where it is possible to source my electricity from clean, renewable energy instead of from coal-fired power plants. That's because in my state (and several others), the utility industry has been deregulated so that competitors can also provide power to meet consumer needs. One of my neighbors, Maurice Belanger, has been buying renewable energy for quite a while. He graciously offered to share his expertise with Big Green Purse readers to help people around the country opt for cleaner energy, too.

Here's his advice. I hope it helps you choose cleaner, greener energy where you live.

  The start of the New Year is time for resolutions. If you live in a state with consumer choice in electricity, you can resolve to reduce your carbon footprint and keep that pledge with just a little bit of time spent researching your options and filling out a form or two on the Web—no need to invest in solar panels or doing anything more complicated than a few clicks of the mouse. 

 

For several years now, I have purchased electricity from a supplier that offers me 100 percent wind-generated electricity. It was surprisingly easy to switch. Yet, talking to my environmentally-conscious friends, I find that many of them are not even aware that they have a choice.

I encourage you to look in to it. Here are a few tips on getting started.

5 Ways to Drive More Efficiently and Save Money, Use Less Gas

 As you shop around to find a fuel-efficient vehicle, you'll notice different average mileage figures given for driving in the city and on a motorway.

Yet there are many other reasons why a car's mileage could vary. Fuel economy can fluctuate not only according to the car you drive, but also to how you drive it.

You might be driving a car that is supposed to achieve 50 mpg, but if you gun the accelerator and leave the engine idling, you won't get anywhere near such mileage in real life.

Here are a few tips to keep in mind to help you maximize your car's fuel economy, courtesy of the fuel-efficiency minded folks at Carsales. Don't forget that fuel efficiency leads up to big money savings at the gas pump. 

1. Stick to the speed limit.

It's a surprisingly common misconception that if you can reduce the length of your trip by driving faster, you'll burn less fuel. In reality, you burn fuel at a more rapid pace when you exceed speeds of 65mph. Wind resistance increases at higher speeds, meaning your car has to work harder to keep up the pace. The most efficient speed you can travel is between 55 – 65mph, after which efficiency will rapidly decrease. Driving at a speed of 85mph would use 40% more fuel than if you drove at 70mph. When on the motorway, try using cruise control to maintain a safe and consistent speed. 

2. Reduce your car's weight.

Another way to boost efficiency is by reducing your car's weight and drag. Remove extra roof racks if you're not using them, because these increase wind resistance. Try to eliminate extra weight from inside the car, as well. If you've been carrying around spare luggage or packages in the backseat or trunk, it's time to clear them out. You can save 1% on fuel for every 45kg/99lbs that you remove from the vehicle. 

Idling Engines Make Air Quality Worse, Especially in Winter

 The colder it gets outside, the more people want to heat up their cars inside - even before they get in the car. Leaving an engine to idle -- in other words, turning the car on and leaving it on when it is parked for longer than about the wait at a stop light -- wreaks havoc on clean air. That's because when your vehicle burns gas, it emits dirty particles and toxic chemicals that combine in the atmosphere to produce acid rain and ground-level ozone or smog that can be very harmful to our lungs. Air pollution is particularly tough on kids, reports the terrific non-profit group Moms Clean Air Force, because they actually breathe faster than grown-ups and inhale more air per pound of body weight. Some communities, like this inspiring group in Nova Scotia, Canada, have banded together to put a stop to idling at schools, sporting events, and shopping malls.

People Like You Are Inspiring Ford Motor Co. To Make Greener Cars

Your demand for more eco-friendly cars is inspiring Ford Motor Company to manufacture vehicles that get better gas mileage, use more recycled materials, tap alternative (and less polluting) fuels, and maybe even help you save energy when you're not driving (think: washing your clothes).

I recently spent two days at the Go Further With Ford Trends Conference at Ford's headquarters in Dearborn, Michigan, where I had a chance to see first-hand what the company is doing to reduce its environmental impact. Full disclosure: Ford paid all expenses for the trip, though did not pay me a fee, is not paying for this post, and in fact required no post at all. I saw the visit as an opportunity to see "up close and personal" what the company is doing to make good on its sustainability claims. Here's what I found out.

Insulate Now to Reduce High Air Conditioning Costs

Most people don't think about insulating their homes until the fall. With winter looming, consumers know that higher heating costs will hit them right where it hurts - in their pocket books.

But guess what? As climate change increases, it is becoming more expensive to cool your home in the summer than heat it in the winter. Here's a copy of my 2012 electricity bill, which shows how much electricity I use month to month and compares 2012 overall to 2011. (I have an electric heat pump for both heating and cooling). I use almost twice as much energy to cool my home in July and August than to heat it in November and December!

All of which is to say that, as we face another blistering summer, now is a smart time to think about insulating your home to keep hot air out and cooled air in.

The Mark Group, a company based in the United Kingdom but with offices in Philadelphia, Delaware, and New Jersey, is sponsoring this post to let you know what energy-saving options you can take advantage of right now. They include:

US-China Greener Consumption Forum Lays Groundwork for Future Projects Together

How can the world's two consumer "superpowers"- the U.S. and China - work together to reduce the impact that consumption has on us and our world?

  That was the topic a capacity crowd addressed on March 22 at the U.S. - China Greener Consumption Forum. The event, held at the World Bank in Washington, D.C. and co-sponsored by Big Green Purse and the International Fund for China's Environment, pulled together scientists, consumer advocates, public policy advocates, and green entrepreneurs to share ideas about strategies to inspire manufacturers to create greener goods -- and get consumers to buy them.

HIGHLIGHTS:

The Forum focused primarily on women because women spend 85 cents of every dollar in the  marketplace – and we’re not just buying cheese doodles and diapers. As I say here on CCTV, the national television network of China, we buy more clothes.  More food.  More cosmetics and personal care products than men. We also buy more electronics, more home furnishings, almost as many tools, just as many cars. Women are spending billions of dollars, day in and day out, year in and year out.

But even with all that clout, we won’t be able to use this power of the purse effectively until we achieve true gender equity worldwide, points that both Ban Li, Deputy Counsel of the Shaanxi Women's Federation, and Liane Shalatek, Associate Director of the Heinrich Boll Foundation North America, made very powerfully.

 Christine Robertson of Earth Day Network facilitated a provocative panel on the impacts consumption has on our health and the health of the planet. Sarah Vogel of Environmental Defense Fund (pictured  right) was peppered with questions after her presentation on the way the toxic chemical Bisphenol-A (BPA) affects the reproductive systems of men and women alike.

Ping He of the International Fund for China's Environment, the co-sponsor with Big Green Purse of the Forum, moderated the session on barriers to sustainable consumption and solutions that help surmount them. Meaningful eco-labels and standards can make a big difference, pointed out Arthur Weissman, President and CEO of Green Seal, especially when those standards are set by an indendent third party (like Green Seal is) whose primary interest is not in selling products, but in helping manufacturers become more sustainable over time.

LISA JACKSON, Former EPA Administrator

 Lisa Jackson's luncheon keynote address was the highlight of the day for many people. As a mom, scientist, and long-time public servant, Lisa has a unique appreciation for the impact consumption has on us as individuals and on society as a whole. She spoke movingly about being the first African-American to serve as head of the EPA and how important it is to bring women as well as people of color and low-income populations into the conversations we're having about pollution and climate change.

Lisa noted that her favorite law is the Emergency Planning and Community Right to Know Act because it empowers people to protect themselves wherever they live. She is also proud of technology EPA has shared with the city of Shanghai to help monitor air pollution there.

Lisa agreed that the way we use both the purse and the pocketbook can inspire manufacturers to reduce pollution and energy consumption.

I am Voting for Barack Obama because We are Greener than We were Four Years Ago.

Are we “greener” than we were four years ago?

 Yes, we are, and Barack Obama deserves a lot of the credit.

 Despite strident anti-environmental opponents on Capitol Hill, President Obama has managed to use the power of his office – deployed primarily through the U.S. Environmental Protection Agency, the U.S. Department of Energy, and the U.S. Department of the Interior – to make our air and water cleaner, to reduce our reliance on foreign oil, to protect our public lands, and to attack the climate change that causes extreme weather events like Hurricane Sandy.

Is his job done? Not by a long shot. But are we making progress? Definitely. I’m supporting the President for a second term because I think he offers our best hope in this election to continue to make progress in the future. 

This all became extremely clear to me earlier this week, as Hurricane Sandy was ripping away part of my roof. While I huddled in my basement listening to the terrifying wind and the torrential rain, I found myself getting mad, not just about what it would cost me to repair the damage, but about the reasons behind this catastrophic storm. Meteorologists, scientists, environmentalists, public health professionals, concerned citizens, and yes, President Obama, have all made the link between burning fossil fuels like coal and oil and extreme weather events like Sandy, let alone Hurricane Katrina and many others. And they’ve tried to throw the weight of their various offices behind solutions that would help wean us from fossil fuels.  

 Meanwhile, conservative forces in Congress and many state houses around the country have blocked legislation that would reduce our dependence on fossil fuels and opposed efforts to increase energy efficiency and the development of renewable energy sources like solar and wind. Bolstered by their conservative colleagues on Capitol Hill and pressured by Tea Party activists, Republican challenger Mitt Romney and Paul Ryan, his running mate, have dismissed climate change, have literally said they “love” coal, and would strive to cripple the EPA if they were elected to office.

 Maybe to some people, this is just “talk.” But as someone who has worked in Washington, D.C. to promote environmental protection during the Carter years, the Reagan years, the Bush 1 years, the Clinton years, the Bush 2 years, and now the last four years of the Obama Administration, I can say, and say unequivocally, that environmental policy consistently fares worse under Republican administrations than under Democratic ones. As Sandy has shown, the planet very much faces a climate change tipping point. Obama is on one side, Romney on the other. For me, siding with Obama is a no brainer.

Has Obama accomplished nearly enough? No.

 Do I wish more change had happened? Of course.

 But we should not let the perfect be the enemy of the good.

ENERGY STAR Essay Contest Shines Spotlight on Energy-Saving Kids

Saving energy is not just for grown-ups. As EPA’s Team ENERGY STAR has shown, lots of kids have become devoted to energy efficiency, too. They’re not shy about telling you why, either. In fact, hundreds of kids have entered the Team’s Share Your Story essay contest .  Several of their posts are featured in this special Team ENERGY STAR bloggers carnival. If you’re inspired by what even the youngest children have learned about energy and climate change (and who wouldn’t be?), why not ask your kids to enter the contest, too? The deadline for submissions is September 17.

Anne at Flour Sack Mama reports, “When I gave my elementary-aged kid a chance to enter the Team ENERGY STAR essay contest, explaining that the focus was saving energy, she gravitated, on her own, to telling how much she loves trees. Sure, she learned the connection from the story of the Lorax.  But I think she gets it, on a deeper level, because she plays outdoors….Of course, the new Team ENERGY STAR initiative does a great job of tying one family's household savings into the bigger picture. Less energy used now means a brighter future for our kids and grandkids and for the place they need to call home long after the rest of us are gone.  At our house, it truly is the little things that we focus on, like better habits of turning off those light switches.  We also made sure to purchase the Energy Star model when we needed to replace our dishwasher.”

 Shane at Environmental Booty proudly  posted the amazing video her young daughter made. The video shows a simulated conversation between two very “hip” sisters, one of whom has a lot to learn when it comes to energy efficiency. “My daughter and I, and even her two sisters, really had fun taking part in the Team Energy Star Share Your Story contest.  Sure, it took finding some time in our hectic lives that was certainly hard to find.  But it brought us all together to go green, created some fun memories with my girls, and gave my Lexie one more reason to feel good about herself.”
