Zero Carbon – Zero Bills

To Stop Climate Change – Start at Home

How to cut your house’s carbon footprint, heating bill and electricity bill to zero.

By someone who has done it: David Green

“Your book is terrific.”
Paul Hawken. Author of “Drawdown: The Most Comprehensive Plan Ever Proposed to Reverse Global Warming”



Our house has a zero-carbon footprint and we pay nothing for electricity and heating. We have “gone zero”. We did this by adding: heat pumps, insulation, triple-glazed windows and solar panels (the “fab four”) . By installing the fab four we are saving so much money that our investments will pay for themselves in about six years. Our return on investment is about 15%. That’s 15% after tax and indexed for inflation. Sure beats my 401k! 

A zero-carbon-footprint house (or just zero-carbon house) is also known as a zero-energy house, net-zero energy house or carbon-neutral house or housing. Over the course of a year a zero-carbon-footprint house generates no net emissions of carbon dioxide. Zero-carbon footprint houses are houses that use very little energy from electricity or heating fuel like natural gas or heating oil. But, because even a single light bulb uses energy, they are do not use zero energy. They can use zero energy net (i.e., after subtracting) the zero-carbon energy produced on site, such as from solar panels.

If you want  a zero-carbon footprint and zero bills for heating and electricity then this web site is for you. By saving money for yourself you will cut greenhouse gas emissions, reduce climate change and combat global warming. It’s true, green is the new gold™.

“Wow! That’s a great gift idea for a gift – give nothing!”. Give a gift with a zero-carbon footprint. A zero-carbon footprint for the lifetime of the T-shirt. It’s the gift that keeps on giving.

Because the technologies of insulation, heat pumps, solar panels and triple-glazed windows are now so good and the subsidies from government are significant, you can, by following the examples in this website, cut the carbon emissions from your house to zero, save thousands of dollars a year on heating and electricity bills, and make a good return on your investment.

We have done it.

David Green’s “fab four” recipe for “making green by going green” i.e., making money by cutting your house’s carbon footprint to zero is:

  1. install 12″ of fiberglass in your attic and in the ceiling of your basement
  2. replace your AC units with heat pumps
  3. when you replace your windows, replace them with triple-glazed windows not double-glazed ones
  4. install solar panels on your roof

These are unsolicited comments I have received on the book:

“Your book is terrific.” Paul Hawken., San Francisco, California. Author of “Drawdown” and one of the world’s leading environmentalists.

“I thought the book was straightforward and clear” B. Mc., Middlebury, Vermont. Leader of 350.org and one of the world’s leading environmentalists.

“Wow that was an awesome book! Super informative on all aspects of the process to get to net zero. I’m very glad I read your book it is such a passion of mine I’ve been wanting to do this for years, you really inspired me to make it happen. Thank you.” D.S., Mastic, New York. Homeowner who is going zero on his house.

“Absolutely loved the book. Very readable for the non-scientist. Fun, entertaining, quite educational for the scientist.” A.N., Weston, Massachusetts. Homeowner who is going zero on his house.

“Thank you so much for your effort and attention here. I feels so fortunate to have met you!” K.A., Arlington, Massachusetts. Homeowner who is going zero on her house.

“I’m very impressed the way you explained the technical terms, the Fab Four and your thoughts on them, leading you to your choice. I was also very surprised when reading the section about old architectural solutions, like verandas, pergolas, deciduous plants, etc. being very often forgotten. Really good stuff.” M.B., London, U.K. Homeowner who is going zero on his house.

It is pure coincidence, or perhaps destiny, that my family name is Green.

David Green’s work on zero carbon houses has been publicized on global news media outlets including ABC, NBC, CBS and Fox and has appeared on the front cover of Green Energy Times,  in the Boston Herald and in Renewable Energy World, as well as the websites of the U.S. Department of Energy, Zero Energy Project, Cool Effects and the Green Home Institute.

David Green, the author of Zero Carbon® Home, has released his second book, Zero Carbon® Pool. Zero Carbon® Pool, just like Zero Carbon® Home, is about how to save money by cutting your carbon footprint. Zero Carbon® Pool is about how to cut your swimming pool’s carbon emissions, heating bill and electricity bill to zero. David Green has done it on his own swimming pool. He found it was quicker, cheaper and made him a better return on investment to go zero on his pool than on his house. Written in the same friendly style and backed by the same scientifically-rigorous and financially-sound analysis as Zero Carbon® Home, this book will help you save money by helping to save the planet from global warming.
