This is a story of electricity beating gas. In 2021, we decided to fix up a duplex in Cleveland, Ohio, that has been in our family for 75 years. After some serious aesthetic and sustainable improvements, we unintentionally ran a multi-year case study in which we experimented with two identical … [continued]
On April 5, 2023, Tesla published Master Plan 3 — Sustainable Energy For All The Earth. It’s 41 pages long, which is exactly 40 pages more than Master Plan 1 and Master Plan 2. We won’t republish the whole thing here, as we know you will want to study it … [continued]
The Inflation Reduction Act does not define the term “free trade agreement,” which has spurred all kinds of tension between the US and its Allies.
Analyzing how we currently use energy in our homes and then incorporating energy efficiencies measures is one of the first steps on the journey to making energy use more sustainable. Corrective measures often include retrofits for old homes, including energy efficiency improvements such as insulation, solar panels, and air source … [continued]
Geothermal heat pumps are a time-tested clean heating & cooling technology with untapped potential. The age of the electric heat pump is well underway. This clean heating and cooling technology has been in use for decades and is widely adopted across Asia and parts of Europe such as Norway where … [continued]
The plan includes a big push in Britain for carbon capture usage and storage, floating offshore wind industry, green hydrogen, small modular reactors, insulation of homes, EV charging infrastructure, and heat pumps. Last week, the Department for Energy Security and Net Zero unveiled a plan to strengthen Britain’s long-term energy … [continued]
A decade old argument in our house relates to the right indoor temperature for our long, chilly, and wet Portland winters. It’s not just a matter of what temperature makes each of us most comfortable (a common household debate) but in our house, where energy savings reign king, it’s also … [continued]
Big news for clean air last week. The Bay Area Air Quality Management District (BAAQMD) adopted amendments requiring the elimination of nitrogen oxide (NOx) emissions from new water heaters by 2027 and new furnaces by 2029. We’ve been hearing about the indoor pollution from gas stoves this year. Gas water … [continued]
ORNL researchers have developed a free online tool for homeowners, equipment manufacturers, and installers to calculate the savings and energy efficiency of ground source heat pump systems compared to traditional heating, ventilation, and air conditioning systems. A tool developed by Oak Ridge National Laboratory researchers gives building owners and equipment … [continued]
Electrification and heat pumps radically reduce the requirement to build new wind, solar, nuclear, hydro, and geothermal primary energy sources.
