Renewable energy is plentiful energy. Burning fossil fuels is a filthy habit, and the supply won't last forever. Fortunately, a growing number of renewable alternatives promise clean, inexhaustible power: wind turbines, solar arrays, wave-power flotillas, small hydroelectric generators, geothermal systems, even bioengineered algae that turn waste into hydrogen. The challenge is to scale up these technologies to deliver power in industrial quantities - exactly the kind of challenge brilliant businesspeople love. Efficiency creates value. The number one US industrial product is waste. Waste is worse than stupid; it's costly, which is why we're seeing businesspeople in every sector getting a jump on the competition by consuming less water, power, and materials. What's true for industry is true at home, too: Think well-insulated houses full of natural light, cars that sip instead of guzzle, appliances that pay for themselves in energy savings. Cities beat suburbs. Manhattanites use less energy than most people in North America. Sprawl eats land and snarls traffic. Building homes close together is a more efficient use of space and infrastructure. It also encourages walking, promotes public transit, and fosters community. Quality is wealth. More is not better. Better is better. You don't need a bigger house; you need a different floor plan. You don't need more stuff; you need stuff you'll actually use. Ecofriendly designs and nontoxic materials already exist, and there's plenty of room for innovation. You may pay more for things like long-lasting, energy-efficient LED lightbulbs, but they'll save real money over the long term.
