Paint your roof white!

White. It's what you wear in the sun to keep cool. Party tents are white. Boats are white. Any kid in elementary school can tell you why: white is a reflective color; light and energy (heat) bounces off of it easily.

Now, through the amazing act of SCIENCE, the Center for Atmospheric Research has concluded from a recent study that painting the roofs of houses and buildings white can drastically change climate (to .7 degrees). Pretty significant, eh? So how does it work? The asphalt that makes up city streets absorbs energy and tall buildings trap heat close to the surface. By painting roofs white, it helps reflect the sun's energy, so the city absorbs less.

How can this help you in everyday life? When retiling your roof, make sure to use light colored tiles. Not planning to do that anytime soon? Use the natural properties of color to help paint your home for your climate. You live in a desert? Use light, reflective colors to direct heat away from your home. Live in a place where it snows 80 percent of the year? Use rich, darker colors to absorb energy and heat, to make your home cozy.

Recycled Redeccorating

Recycling doesn't have to stop at glass, plastic, or cans. Take into consideration that things that can be reused get thrown away ALL the time. One person's trash is another's treasure, right? When renovating your home, you can use lots of recycled products to make your shabby house chic. Here are some ideas to turn your renovation quest into a recycling bonanza.

Antique stores, flea markets, and yard sales often have old cabinets, furniture, and recycled wood that you can reuse. Sand down, resurface, and stain cabinets to make them look like new. Cover an old armoire door with plastic and you've got yourself a ghetto-sled!

Recycled lumber can be used for a multitude of projects, including flooring, coffee tables, or wall accent pieces. Transform an old door into a headboard for your bed, or a new desk.

Plastic bottles can be recycled into an awesome light fixture. Heck, light fixtures can be recycled, rewired, and reused to give your place that vintage feel.

Use your imagination. Pretty much anything you find can be reused in some way or another. Go wild. Try turning old LPs into a fruit bowl or a room divider, use old shirts to make a quilt, or make a Devo hat out of a red bucket.

If you want to recycle and reuse materials, but aren't much of a thrift store hound, check out Habitat ReStore outlet (www.habitat.org/restores/default.aspx), which supplies reused and donated materials for renovations.

Farm to Table Eating

Food is one of those things that can evoke a love–hate relationship. Depending on how and where food is grown and how it is prepared, it can make you sick, fat, or utterly euphoric. With the proposed enactment of the Food Safety Modernization Act, the FDA can regulate the quality of the food that goes into our bellies, but how much will that matter? Spinach can still give you e-coli, and beef, mad cow disease.

This is a good time to get into the groove with locally grown food that leaves a local farm and lands directly on your table, or the table of your local eatery. Foodies have been onto this idea for a long time, understanding the importance of locally grown food and the ways they are prepared. You can join your local Community Sponsored Agriculture association to get local food at home. Check out sandiegoroots.org for more info.

Now for those of you who don't have the time, patience, or skills to turn a nice basket of CSA food into a delicious meal, fear not! There's a plethora of restaurants that are popping up in San Diego that serve home-grown foods. North Park seems to be a great hub for restaurants serving local and sustainable foods. Try out The Linkery, Sea Rocket Bistro, Ritual Tavern, and El Take It Easy, and do some research to find some other great restaurants in your neighborhood. sandiegoroots.org/restaurants.html

PaintGreen Cares

Community is a cornerstone of the PaintGreen mission, and charitable donations are important. Many companies claim to help the community, but rarely follow up on their pledge. PaintGreen has extended their pro bono work (not to be confused with pro Bono) to help the youth of San Diego by giving them vibrant living and learning spaces.

PaintGreen committed to painting all the classrooms in the current Xara Garden School facility, located in Allied Gardens. Xara Garden School is a charter school committed to giving children the freedom to learn language, arts, and nature in a student-driven environment. Once Xara Garden School selects its permanent location in two years, PaintGreen will offer their services again, to help make the learning environment as whimsical and entertaining as possible. For more about Xara Garden School visit www.xaraschools.org. In addition to painting the Xara Garden School, PaintGreen reinvigorated the Spring Valley Community Center, to improve the surroundings for the kids who attend.

One of the major organizations PaintGreen supports on a monthly basis is Cecily's Closet, a non-profit organization that helps families with special-needs children. Cecily's Closet provides donations to families in need, and PaintGreen is fundamental in providing room makeovers to help families and children enjoy their homes.

Other local organizations benefit from PaintGreen's generosity, including the Cucina Club, a local shipping-container turned full-service-kitchen, to help feed those who can't afford to feed themselves.

PaintGreen is committed to supporting the people of San Diego with their painting needs and will continue to do so well into the future.

Tips for choosing a contractor

You hear horror stories about people hiring contractors and they either do a sub-par job, steal all of their belongings, or break things in the house and don't have liability insurance to cover the cost (thanks to the interwebs, there are myriad sites dedicated to these torrid tales). Don't get caught in the same situation. Here are some tips to help you get a quality contractor who does quality work.

DO ask for a contractor's license number and check it against the Contractor's State License Board website (www.cslb.ca.gov) to make sure they are a contractor in good standing without any complaints against them.

DON'T choose a contractor based on looks. Two words: Ted Bundy. Enough said.

DO check with the Better Business Bureau in your city (sandiego.bbb.org) to make sure the company you're looking at is in good standing with the city.

DON'T go with the cheapest contractor. Oftentimes they will bid low and skimp on materials or craftsmanship to meet that bid. If they can't, they will often line-item everything, including the toilet paper they bring to the job.

DO ask for references or check review sites like Yelp (www.yelp.com) or Angie's List (www.angieslist.com). Word of mouth is one of the best sellers. Most companies that do quality work don't need to advertise much, because they get most of their business through referrals.

DON'T change job specs halfway through the job. Make sure you have solid plans before you hire a contractor, and make sure to discuss any changes you want to make up front. Changing late in the game draws out the timeline and drives up cost.

DO get a quote and timelines to make sure they fall in line with the scope and budget of the project. Make sure to specify which types of materials you want on your project in the contract, so lesser materials can't be substituted in an attempt to lower the cost of the project.

DON'T be pressured into using a contractor. If they insist on an immediate yes or no for a quote, run for the hills. A quality contractor will honor a deal, even if it takes you a week to think things over. Hiring a contractor is like hiring a ghostwriter for your memoirs: make sure they can tell your story how you want it.

No Silver Bullets...


Lifted from terrapass.com By Erin Craig 5/26/2010

I heard a luncheon speaker last week who channeled James Hansen as he asserted that mitigating climate change is, more than anything else, about coal. And that actions short of shutting down all the coal plants are something between a palliative and an unwarranted distraction.

This line of thinking couldn’t be more right and more wrong at the same time.

The math is incontrovertible. First, here’s a quick study on the relative quantities of greenhouse gases emitted when fossil fuels are combusted:

Emissions by Fuel.jpeg

Next, here’s the most recent data and projections on fuel use from the US Energy Information Administration:

Fig2 World Energy Use by Type.jpeg

So, yes, coal is exceptionally rich in greenhouse gas emissions, and unless there’s a meaningful intervention we’re going to burn a whole lot of coal.

But what is the best way to bring about that intervention? Does anyone really think we have the political will and the economic stamina to self-impose the short-term but serious and widespread socioeconomic dislocation which would result from swift closure of hundreds of coal-fired power plants in the US, never mind stemming their growth in China and India?

Coal is abundant and available domestically in China, the US, India and Russia, not coincidentally the four largest users of coal. And, though I don’t like my own conclusion, I simply can’t envision a future where nations with abundant domestic energy reserves don’t make use of them.

That’s why I’m increasingly a fan of aiming at better ways to use coal. Carbon capture and sequestration is one approach that’s received much attention(pdf). Another is new-age coal-to-liquid technologies, including some which combine coal with biomass to lower the carbon footprint of the resulting liquid fuel. Interestingly, coal-to-liquids research is the recipient of substantial US military funding, as the military has an important interest in securing domestic liquid fuels and the foresight to push suppliers to low-carbon solutions.

We do need to intervene on a grand scale in the coal combustion cycle. To make that happen, we need to step away from all-or-nothing rhetoric, continue to demonstrate our willingness to change by taking personal actions no matter how individually small, and create not only the incentives (that price on carbon we talk so much about) but the technology path to the low-carbon future.

Bill Gates is pretty much right.

By Adam Stein | March 2, 2010 Lifted from Terrapass.com:

For my valedictory post, it’s tempting to engage in a little big-picture think. I’m also still mulling the general reaction to Bill Gates’ TED talk, which seemed to me both entirely too hostile and also reflective of some of the lingering pathologies in the environmental movement. So, yeah, this is going to be a bit of a ramble.

Let’s start by putting forth two propositions:

  1. In the future we will be richer (and that’s a good thing)
  2. Technology will save us from climate change (if anything does)

Both of these statements are very probably true, but they tend to raise hackles among greens unless they’re wrapped in thick layers of caveats. Now, there’s nothing wrong with a nice caveat – I use them all the time myself – but, as the some of the nitpicking reactions to Gates’ talk reveal, it’s possible to cling to them too tightly.

First, wealth. Nicholas Stern, former chief economist of the World Bank, caused a stir in 2006 with the release of a report claiming that, if left unchecked, climate change could knock a full 20% off global GDP over the next two centuries. The Stern Review was both more detailed and more dire than previous attempts to quantify the economic impact of climate change. Although the report immediately set off a huge methodological squabble, the effect was nonetheless electrifying: a respected economist, working under the auspices of the British government, had declared that the costs of inaction on climate change massively outweigh the costs of action.

The little-noted kicker is that even in the terrible 20% scenario, the world will still be far richer than it is today. Not nearly as rich as it could or should be, but better off than we are now.

It’s fair to point out that the impacts of climate change will be unevenly distributed, and that measures of GDP fail to capture these effects. But it’s also important to note that, even as the developed world suffers through a calamitous financial crisis, these are the best of the times for the world’s poor, and the situation is likely to keep getting better (emphasis added):

World poverty is falling. Between 1970 and 2006, the global poverty rate has been cut by nearly three quarters…Although world population has increased by about 80% over this time (World Bank 2009), the number of people below the $1 a day poverty line has shrunk by nearly 64%, from 967 million in 1970 to 350 million in 2006. In the past 36 years, there has never been a moment with more than 1 billion people in poverty, and barring a catastrophe, there will never be such a moment in the future history of the world.

Second, technology. Gates has gotten some (deserved) criticism for making disparaging remarks about energy efficiency, but his larger point is indisputable: we can’t conserve our way to zero emissions, so the long-term solution to climate change necessarily requires producing all of our energy from renewable resources. I might also add that the vast majority of emissions reductions from efficiency and conservation will also come from technological improvements.

In a response to Gates’ speech (“Why Bill Gates is wrong”), David Roberts complains that the focus on technology distracts from innovation in other areas, such as policy, systems integration, infrastructure development, finance, and even social norms. But, look: almost all “distraction” arguments are really just quibbling, and this one is no different. Although whizzy gadgets might first come to mind when we think about innovation, in truth society is quite good at recognizing and rewarding innovation that has very little to do with technological breakthroughs. In fact, it’s fair to say that greater rewards accrue to the people who disseminate and apply new technology to age-old problems than to those who invent it. Neither Amazon nor eBay invented the internet. They just used it to make a better way to shop. Likewise, the Passive House standard is just the systematized application of well-understood design principles and low-tech efficiency improvements. But it still represents technological innovation.

Part of the reason that greens push back on these truisms about wealth and technology is that many anti-environmentalists use glib versions of these arguments to argue for complacency or, worse, to push a noxious policy agenda. Such efforts deserve vocal opposition. But Bill Gates doesn’t. His speech included a call for carbon pricing, an endorsement of Al Gore’s most recent book, a nod to the problems of deforestation and cement production, and a strong plug for regulatory reform, energy efficiency, solar and wind energy. For a short speech focused mostly on a single energy start-up, it did a remarkably good job of covering its environmental bases.

So why the piling on? In part, Gates raised ire because he didn’t spend a lot of time on the usual pieties. Absent from his talk was any moralism about western lifestyles. His call for “energy miracles” was uncomfortably close to a call for silver bullets (something all good greens know to boo). He spoke like an engineer trying to solve a really big engineering challenge. And in so doing, he triggered some of the cultural grievances that often underlie discussions of energy consumption. I wrote recently that the environmental issue I care most deeply about is “finding a way to sustain nine billion wealthy and fulfilled human beings on a planet that hasn’t been completely despoiled.” This seems like an uncontroversial stance – which part would you argue with? – but it nevertheless prompted glib and entirely predictable comments about McMansions.

My guess is that Bill Gates’ formulation of the problem sounds really good to people who are worried about climate change but aren’t necessarily committed environmentalists. And frankly, that’s more important than being right on every single technical point, or achieving the officially sanctioned balance of tone and emphasis. If we want the issue of climate change to escape the green ghetto, we would do well to set cultural grievances aside. Partly this is just smart politics. People really don’t want to be lectured about their sins. But more importantly, such grievances lead us down the wrong path. Asking for a worldwide movement of people voluntarily and significantly downgrading their lifestyle to spare the earth is to pray for an energy miracle far beyond anything Bill Gates can conceive.

There is good news here. With the right policies in place, and the right research and development, and with swift innovation on many different fronts, future citizens will be transformed into eco-warriors by default. My grandmother refuses to touch a computer, but one-year-old babies can use an iPhone. Likewise, tomorrow’s kids are going to be energy geniuses and environmental savants, not because they’re any smarter or more enlightened than we are, but because the structure of their society and their technology and their markets will make it so.

At least, that’s my hope. We need to push forward in a variety of ways to bring such a vision to pass. And we need to shed some of the grim moralism to build a stronger environmental movement. Even if I’m pretty sure tomorrow is going to be better than today, I don’t think we can take anything for granted.

Warmest January EVER

By Tim Varga... lifted from terrapass.com

Europe is freezing and the Eastern U.S. just experienced a snow-pocolypse, so surely the whole global warming thing must be wrong, right?

Sorry, Sen. Jim Inhofe (R-OK), but global warming is still happening, even though it snowed in January (of all things). According to the latest satellite data analyzed by climate scientist and IPCC member Neville Nicholls, this last January was hotter than any previously recorded January.

It’s not just January, either - it was the entire decade:

The World Meteorological Organization (WMO) said in December that 2000-2009 was the hottest decade since records began in 1850, and that 2009 would likely be the fifth warmest year on record. WMO data show that eight out of the 10 hottest years on record have all been since 2000.

It’s hard, sometimes, to accept pervasive trend data as accurate when personal experience contradicts it. In a similar way, you might be understandably skeptical of your town’s assessment that crime is down if you’ve just been robbed and so has your neighbor. It’s crucial, though, to remember that snow storms in winter are weather events, and global average temperature is a measure of our whole climate. No single weather event - including disastrous ones like Hurricane Katrina or the recent blizzards on the East coast - are directly caused by a changing climate. But scientists are telling us that increased warming of the climate can and will lead to more and stronger weather events, both hot and cold.

Is Earth actually warming?


By William Yeatman and lifted from globalwarming.org

Global warming may or may not be a problem. Man may or may not be driving it. Given the uncertainties, a significant amount of global regret may apply if we divert too much of our global wealth to solving what may be a non-existent or trivial problem, especially if that diversion mires billions in poverty. On the other hand, we may also regret not doing anything if man-made global warming does turn out to be a problem. It is therefore prudent to examine what steps we can take that would prove beneficial whether or not anthropogenic global warming turns out to be a problem. These steps can be termed “no regrets” policies.

What makes a No Regrets Global Warming Policy? A global warming policy can be termed “no regrets” as long as it:

  • Reduces the amount of greenhouse gases emitted into the atmosphere, or
  • Mitigates, prevents or reduces a harm associated with global warming, or
  • Provides greater capacity for dealing with problems associated with global warming
  • Without imposing significant cost or diverting economic activity.

Top Five “No Regrets” Policies

1.) Eliminate all subsidies to fuel use.
Subsidies to energy R&D cost taxpayers millions of dollars while producing minimal benefits. While these programs may be relatively small given the size of domestic energy markets, they serve little, if any, useful purpose while subsidizing large corporations at taxpayer expense. The potential threat of global warming, whether it is real or not, is simply one more reason to eliminate these subsidy programs. An international agreement aimed at ending energy subsidy with binding targets would be a significant victory for emissions reduction. Unlike Kyoto, which forces an energy starvation diet on its participants, such a treaty would be a move to combat energy obesity.

2.) Repeal the Federal Flood Insurance Program.
Much of the concern over global warming’s potential for harm in the US relates to sea level rise and the flooding that will result. However, much of the investment in potentially vulnerable areas is a result of the Federal flood Insurance Program. This program encourages building in vulnerable areas by acting as a moral hazard: people take greater risks because the government has said it will help bear that risk. Reform would reduce the moral hazard connected with building on vulnerable land, transferring the risk from the taxpayer to the private sector, which is likely to take a more realistic view of the issue.

3.) Reform Air Traffic Control Systems.
Greater demand for air travel means more flights, which means greater fuel use and increased emissions. Yet, the current government-operated system of air traffic control, based on a 1920s-era system of beacons, may hinder innovations that could reduce fuel use and emissions. As a general rule, the shorter the flight, the less fuel will be consumed. Yet neither airlines nor pilots have the freedom to choose the most direct and economical route. Giving pilots freedom to map their own course is an attractive and desirable change in the eyes of the industry, and the impact on the environment would be tremendous. As well as saving considerable amounts of greenhouse gas emissions, the policy will deliver significant benefits in terms of time and expense to the US economy. By obviating significant reductions in service levels associated with more routine applications of emissions reduction policy, it is to be preferred to that approach.

4.) Facilitate Electricity Competition.
By rejecting the model of central regulation and allowing suppliers to meet their customers’ needs more exactly while relying on distributed generation, energy waste and the associated emissions will reduce considerably. This reduction in waste will prove economically beneficial even if emissions themselves do not cause problems.

5.) Reduce Regulatory Barriers to New Nuclear Build.
There is no other technology than nuclear that is proven to be capable of providing emissions-free energy at the scale required to make significant reductions in carbon emissions. The problem is that thanks to anti-nuclear activism by environmentalists in the 1970s, it takes a very long time to build a nuclear plant. This pushes development and construction costs up to the level where it is not economically competitive with higher-emitting forms of electricity generation like coal and natural gas. According to the nuclear energy institute, it takes 10 years from concept to operation to build a nuclear plant, and only four of those are construction, the rest is permit application development (2 years) and decision-making by the Nuclear Regulatory Commission (4 years).

Brrr... what happened to Global Warming?

By Pete Davies and lifted from Terrapass.com

It’s tempting to point out that global warming doesn’t necessarily mean that it’s always going to be warmer. It’s why many of us prefer the term “climate change”, after all. Yes, global average temperatures are moving upwards, but that doesn’t mean that it’s always going to be warmer everywhere, just more volatile.

But actually this current cold spell has nothing to do with climate change. Apparently it’s caused by Arctic oscillation: higher than average pressure over the Arctic is pushing cold air further south than is usual in the winter.

Dr. Walter Meier of the National Snow and Ice Data Center in Colorado tells the New York Times that while we’re freezing here, it’s been much warmer than normal in the Arctic, as high as 15 degrees above average. It “probably roughly cancels out,” Dr Meier says.

There’s no shortage of blogs (I don’t want to give them link credit) that have seized on the cold snap (picture credit to one of them) and used it to discredit global warming. Meanwhile, the denier-supporting media has even managed to back up a claim that we’re in for 30 years of cooling. (The scientist didn’t actually say that.)

Nobody seems very clear on when an Arctic oscillation is likely to happen, or why. What does seem clear however, is that it’s unrelated to global warming. Or cooling. It’s happened before and will happen again. Tell your friends — you never know who might be having their doubts.
