As technology improves, the s most energy-efficient product at the time of purchase can soon become the most energy-inefficient product.

Several issues it addresses include: metering and reporting, energy-efficient product procurement, energy savings performance contracts, building performance standards, renewable energy requirements, and alternative fuel use.

It's the quick and easy way to spot the most energy-efficient products on the market.

Government agencies could be required to procure energy-efficient products.

Some even argue that producing energy-efficient products, such as light bulbs, actually simulate more demand, resulting in more energy being purchased for conversion into light of the same strength.
