Energy efficiency is at the core of all green building certification programs. It’s time to ratchet up these modest improvements to make homes as green as they can be by operating them entirely with clean energy.

Natural gas is no more natural than coal or petroleum, and must be phased out rapidly. This means that all new buildings must be powered by clean electricity from renewable sources. It’s just common sense.

The future is electric and the power will come mostly, if not entirely, from renewable sources. In Part Two of Energizing the Green New Deal, we get specific about strategies that utilities and heavy industry can utiliz e to address climate change and make a profit at the same time. Utilities will play a central role in guiding development of renewable resources and efficient ways to deploy them. Industry may present the greatest challenges, but there are existing technologies to smooth the transition, plus smart incentives and new technologies in the pipeline.

High performance homes are a great investment for the homebuyer, no matter how you measure it, as described in Part One of this series. But there are also many non-monetary benefits for the homeowner. These highly efficient homes are a win for everyone involved, including builders, realtors, lenders and utilities. Here’s a powerful list.

In Part One of this two-part series we show the real financial returns for zero energy homeowners. — “A penny saved is a penny earned,” according to Benjamin Franklin. Let’s start thinking about energy improvements as investments that bring a financial return. Here are four ways to evaluate the financial performance of zero energy homes. They all demonstrate that zero energy homeowners benefit financially, making zero a wise investment.

The move away from fossil fuels requires that buildings and vehicles be powered by electricity from renewable sources, such as wind, solar, etc. All-electric homes in cold climates present a challenge for comfort and cost, but those barriers have fallen to recent developments in design and technology - making all-electric homes desirable even in cold climates.

Building materials and equipment play a key role in the efficiency and affordability of zero energy buildings. This is why we’re proud to introduce the Zero Energy Project Product Directory to help builders identify appropriate products and to stimulate the supply chain to provide products that will draw the building sector toward greater energy efficiency.

Every buyer wants an energy-efficient home, but there are so many factors to consider that many buyers become overwhelmed. Did you know that the energy performance of any home can be expressed in one simple-to-understand number? Here it is.

To stay competitive, a production builder must find a good balance between cost, price, and profit. Here’s the story of one builder who has successfully added high-performance, clean energy features to their standard offering. More importantly this builder has developed an elegant solution to the challenge of solar-powered homes producing energy when it is not needed by the grid.

A new study shows that the cost of zero energy homes is very close to that of homes built to code. Best of all, costs are dropping and the trend is expected to continue.
