Today the Department of Energy (DOE) announced the award of 16 new Indefinite Delivery Indefinite Quantity (IDIQ) Energy Savings Performance Contracts (ESPCs) that could result in up to $80 billion in energy efficiency, renewable energy, and water conservation projects at federally-owned buildings and facilities. ESPCs help to meet the federal government's energy efficiency, water conservation, and renewable energy goals. The federal government is the largest single user of energy in the United States and these awards demonstrate a commitment to sound government stewardship by recognizing efforts to save energy, reduce federal energy costs, cut greenhouse gas emissions, bring more cutting-edge technologies to use, strengthen national security, and create a stronger economy.

How to conserve water using a water timer.

British inventors have designed a washing machine that takes eco-friendliness to a new level: it uses just a single cup of water to wash a load of clothes. Instead of water the Xeros machine uses thousands of special plastic chips (about 44 pounds' worth) in each wash, and when that single cup of water is heated, these chips absorb the dirt-including tricky stuff like coffee and lipstick. The chips are removed when the wash ends, and can be reused up to 100 times. Though it's still in prototyping, the inventors are intending to commercialize their machine, and it may even hit the shops next year for a price similar to conventional machines.
