Since before the dawn of civilization, humans have stayed comfortable by harnessing the forces of nature. These principles can also be applied in today’s homes and buildings to reduce or eliminate energy used for conventional air conditioning.

On new and retrofitted roofs, you can now use aesthetically pleasing solar shingles to keep the weather out and generate renewable energy. They’re more cost-effective than you may think. We compare costs with other roof options and review pros and cons to help you decide if they are right for you.

Thoughtful zero energy design and material selection is only the first step to reducing the climate impact of a new building to zero. In the end, the building needs to generate enough positive energy on site to compensate for both its embodied carbon and its operational energy.

New homes and buildings will stand for decades, if not centuries. The carbon emissions embodied in the building materials and resulting from the manufacturing and construction processes must be factored into their overall carbon footprints. These four steps will get us started on the path to zero carbon.

Not everyone lives in a place or a situation that allows them to install their own solar panels. If you are among them, fear not! Here are four ways to source renewable power or at least compensate for the carbon emissions of the energy you use. These four methods make zero energy homes and buildings possible for everyone.

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.

Energizing the Green New Deal Part Three is the final installment of our three-part series on realistic, primarily market-based methods for creating a zero carbon economy. Buildings are responsible for about 40% of greenhouse gas emissions and transportation for another 29%, so there is a lot of work to do there. Agriculture and forestry are two more fields that must be addressed.

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.

Energizing the Green New Deal: Part One of a Three-Part Series. Realistic climate action requires clear goals and objectives and an achievable timeline. If it is to have any chance of becoming reality, it must also align with the free enterprise system in which most of the work is accomplished by the private sector. Here is a comprehensive set of specific goals and objectives plus how best to achieve them, with the least government involvement.

The amount of Renewable Energy Tax Credit for residential and commercial buildings will soon begin a gradual decline. If you’re thinking about solar, NOW is the time to act!

Swimming pools are great fun, but they have high running costs and a high carbon footprint. David Green cut both. Now his pool running cost is zero and so is its carbon footprint.

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.
