Zero Carbon – Zero Bills
To Stop Climate Change – Start at Home
Zero carbon homes save money, improve health and substantially cut emissions of carbon dioxide. I have cut the carbon dioxide emissions of my house (and swimming pool) to zero, I pay nothing for heating or electricity and our indoor air is clean and fresh. By following my “Fab Four” recipe, which is summarized below, you can do it too and help us get to net-zero carbon by 2050.

David Green is a scientist by training (BA in physics from Oxford University) and has spent his career in business (MBA from Harvard Business School) so we only did things to our house that made both energy sense and financial sense. I found that a lot of the conventional wisdom is wrong. What we did not do is as important as what we did do.
I regularly do free webinars called “Zero Carbon, Zero Bills” in conjunction with local environmental or sustainability organizations like towns or libraries. If you are part of a local group and would like to host a webinar please let me know at dgreen@greenzerocarbon.com I can take care of all the registration and hosting so all you need to do is add the audience. I give away a free copy of my book Zero Carbon Home to all attendees.
You can watch a recorded version of a prior webinar (which includes EVs and the IRA subsidies) here:
Reviews of my “Zero Carbon, Zero Bills” webinar included, “Minute-for-minute, point-for-point, one of the best webinars I have ever attended. Thank you!”, “David is a true inspiration and asset to our community. He inspired us to get solar panels and a new front door”, “This is like a masterclass in ZeroCarbon”, “Thank you soooo much for the sensible advice and your fabulous resources!!” and, although this next comment is a little flowery, it does express the sentiment of many other comments, “Your contribution to Greening America is great and will probably help our survival as a species a bit longer than expected”.
I do all my webinars for free and every attendee gets my book for free too. I do this to try to help save the planet from global warming. If you are part of a local sustainability, environmental or energy conservation group and would like to host a webinar please contact me at: email David Green to arrange it. I can take care of all the arrangements for Zoom hosting and registration so all you need to have is an just add the audience!
Our house is a zero-carbon house. We have achieved net-zero carbon and done so profitably. We achieved this in 2019, a long time before the 2050 goal of “net-zero carbon”. We did it using off the shelf equipment installed by local contractors. It wasn’t even that hard to do. It is just like baking a cake. If you tried to bake a cake with no knowledge of the ingredients and quantities you would make a lot of bad cakes. But if you have a recipe to follow, anyone can make a good cake. It is the same with cutting carbon emissions and saving money on houses. It is a lot easier to follow a proven recipe. My recipe is proven by having been applied to about 35 different houses ranging from 1,500 square feet to 14,000 square feet, from 1790’s New England colonial farmhouses to brand-new construction designed to be energy efficient, and heated by every conceivable fuel. I have never failed to help people cut their carbon emissions and bills substantially.
I hope my Fab-Four recipe for going zero (explained in both the books and the free webinar) is detailed enough for you to cut your bills substantially and get to a zero-carbon footprint on your own. However, if you feel you need some further guidance in going zero, then please see my Zero Carbon® Home consulting service described below.
For several years I have consulted to homeowners who asked for my help in cutting their energy bills and carbon emissions. So far, I have helped about 35 homeowners to do so. A typical project used to cost the homeowner about $1,500 but I have invested in the software to cut down the time taken and I now offer the same service for $199, see below. Homeowners give me great reviews, like the following:
“Working with David Green was an absolute pleasure, he guided me through the process with his experience in lowering my energy expenses and my overall carbon footprint.” DS, Long Island, NY.
“I wholeheartedly endorse David Green as a home energy consultant. He used his expertise in energy efficiency to focus on cost-effective solutions. As a result of following his suggestions, my house has significantly reduced energy consumption along with improvement in the overall comfort of my home.” – LA, Westwood, MA.
“David Green is the most knowledgeable person I have found when it comes to giving advice on making the transition from a fossil fuel heating system to a heat pump system. David is friendly, warm, and thorough. He was focused on saving me money and, by looking strategically at my situation, he helped me realize that I did not need to replace my entire heating system, as I had originally thought. I highly recommend David as a consultant. He will enable you to make the best and most financially sensible decisions about insulation, heat pumps, and solar panels.” – RR, Arlington, MA.
“we found your report to be very helpful indeed!” – ML, Needham, MA
I now offer my consulting service to homeowner for a flat fee of $199 per home. You can download an example of the report (which now includes the benefits of the Inflation Reduction Act) here:
Please email me at dgreen@greenzerocarbon.com if you are interested in this service. The only information I need from you is your address and the type of heating fuel you use, e.g., natural gas, heating oil or propane.
This service is currently only available in MA, for detached single-family homes. There are other limitations stated in the report. If your house is not in MA, or is a double or triple decker or an apartment, or otherwise does not meet the criteria listed in the report. I can still help you but not for the same price. Please email me at: dgreen@greenzerocarbon.com if you are interested.

In addition to the investment returns of 15% after tax (sure beats my 401(k)!), according to a large body of academic research, our house price has increased by between 8% and 14%. Even the low-end estimate greatly exceeds what we invested in the Fab Four. Hence you no longer have to wait until the savings pay for the investment in the equipment, you can get your money back as soon as you sell your house. In fact, adding the Fab Four is now a good way to prepare your house for sale.
On this site there are now written answers to over 300 questions that were asked by people like you on one of my webinars. These include topics like: using heat pumps with hot-water radiator systems; dampness, moisture, humidity and rotting cathedral ceilings; ducted and ductless heat pumps; the carbon footprint of natural gas, heating oil and propane; cutting carbon emissions from swimming pools; the return on investment from batteries like the Tesla Powerwall; net metering for solar panels and why adding insulation to walls is rarely a good idea.

I have written three books on how to get to zero carbon, zero bills. You can get my first book, Zero Carbon® Home, for free by attending my free webinar. My second book, Zero Carbon® Pool is not available for free but you can buy it from this website. My third book, the Special COVID19 Stuck at Home Edition of Zero Carbon® Home you can get for free by entering the code COVID19 at checkout. All attendees at my highly-acclaimed webinars get a free copy of the e-book version (for iPad/Nook or Kindle) of my equally highly-acclaimed book Zero Carbon® Home. When Paul Hawken, the author of “Drawdown: The Most Comprehensive Plan Ever Proposed to Reverse Global Warming” reviewed the book he said, “Your book is terrific.” Bill McKibben has also endorsed the book as have many people I have helped to cut their bills and carbon emissions.
You can see a recording of one of my early webinars on YouTube here: https://youtu.be/9ee-rcrvlM4 This webinar includes an explanation of how the Fab Four work. In the next link, https://youtu.be/vz13y-MB23M you can watch my latest webinar which now includes electric vehicles (I own a Tesla Model S and a Ford F150 Lightning) and the very generous subsides in the Inflation Reduction Act or IRA. To get the new material in I had to take out the explanations of how the Fab Four work.

The T-shirt is made from 100% organic cotton grown grown in the USA. It is also sewn in the USA and uses no bleach or dyes. It costs $19.99 and is only available in the USA.
If you are looking for how to make money by cutting the carbon footprint of your swimming pool to zero, (which I have also done – it was quicker, cheaper and made a higher return on investment to go zero on my pool than on my house) please click here: Zero Carbon® swimming pool
Getting to a zero-carbon / net-zero home.
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:
- install 12″ of insulation in your attic and in the ceiling of your basement
- replace your AC units with heat pumps
- when you replace your windows, replace them with triple-glazed windows not double-glazed ones, or add low cost “fit-from-the-inside” window inserts
- install solar panels on your roof
