Solar panel startup companies are struggling in the current recession, according to Sustainable Industries. Startups, some of which are sitting on genuine innovations to make solar panels more efficient, can’t find the funding they need to get off the ground. Prices for solar panels have dropped precipitously lately, which is great news for everyone except for the startups that were banking on high prices and increased demand. Some of the companies have begun laying off workers, while others are radically shifting their business plans in order to survive.

What’s the thirstiest industry in the United States? If you thought of agriculture, you’re spot on. But coming in second—guzzling 40 percent of U.S. freshwater withdrawals—is a surprisingly different undertaking: electricity.

Environmentally motivated researchers and policymakers are just beginning to grasp the importance of illuminating the complex relationship between water and energy, Sustainable Industries reports. The clock is ticking. By 2025, the United Nations forecasts half the world will meet with freshwater shortages. By 2050, upgrade that pinch to scarcity spanning three-quarters of the planet. And, oh, wouldn’t you know: All forms of energy production require water (and on the flip side, heating, treating, and distributing water requires energy too).

“Increased implementation of renewable power sources is key to securing future water supplies, but when it comes to water use, not all renewables are created equal,” writes Sara Stroud, SI’s Bay Area correspondent.

Wind and solar photovoltics are among the lesser offenders; they require only one gallon of water for each megawatt hour of electricity produced (excluding water used in manufacturing). (A megawatt is one million watts, and one megawatt hour could power 400-900 homes for that hour.) Compare that to corn-derived ethanol, which sucks anywhere from 5 to 2,000 liters of water for each liter of fuel. That higher number comes courtesy of agriculture undertaken in arid states, like California and Colorado.

“Federal incentives happened so quickly without evaluating consequences,” Dulce Fernandes of Network for New Energy Choices told SI. “If we are investing in alternatives, we have to get it right.”

January means list time. Everyone feels entitled to publish an annual top ten list around the New Year, looking back on 2007’s notable scientific discoveries, blunders, and cat videos. But Sustainable Industries is looking ahead. The monthly green business magazine, nominated for a 2007 Utne Independent Press Award for its environmental coverage, has put out its annual Trend Watch, with in-depth articles on eight green business trends we can expect to see in 2008.

One thing to anticipate in 2008 is growth in the green building products industry. Despite worries over the U.S. housing slump, the green building market has been growing rapidly, with the market for green building materials increasing a whopping 23 percent annually from 2004 to 2006. Sustainable Industries attributes the growth to consumer demand, stricter building codes, and the reduced operating costs that come with green buildings.

But consumers aren’t satisfied with just living in green buildings—they also want to be able to keep tabs on their energy consumption within the home. Which is why Sustainable Industries predicts we will see an increase in technology that gives consumers easy access to energy usage information: “A growing number of savvy companies are providing value-added services that help individual users make sense of the environmental data available, using the now-ubiquitous cell phones, PDAs, laptops and other personal communication tools available.” One such tool, featured in Good magazine, shows how much energy is sucked up by common household appliances even when they are turned off. And Sustainable Industries reports that Nissan plans to add displays to vehicles that tell the driver how their acceleration and braking behaviors affect fuel efficiency.

Other predictions for 2008? Expect to see advances in battery operated cars, increased reliance on renewable energy sources, and a consolidation of green media sources.
