Paul Gipe
is an author, advocate, and analyst of the renewable energy industry. He has written extensively about the subject for the past four decades, receiving numerous awards for his efforts. Gipe has lectured before groups from Patagonia to Puglia, from Tasmania to Toronto, and from Halifax to Husum. He has spoken to audiences as large as 10,000 and as small as a private presentation for Vice President Al Gore. Gipe is well known for his frank appraisal of the promise and pitfalls of wind energy, including his stinging critiques of Internet wonders and the hustlers and charlatans who promote them. He led the campaign to adapt electricity feed laws to the North American market–the same policy that has stirred a renewable energy revolution in Germany.

Cascade Community Wind Company?
As part of my continuing project to document early wind projects, I am seeking information on the Cascade Community Wind Company. NREL’s Owen Roberts sent me two photos of a reconditioned Vestas V17 near Ellensburg, Washington. Roberts provided the coordinates: 47°06’03.7″N 120°44’59.3″W. The lone and lonely turbine stands across Thorp …
Electrification: Tracking Down a Mystery Outlet We have a mystery outlet in the kitchen. It’s an old style outlet and clearly designed for 240 volts.[1] It’s not you standard 120 volt duplex outlet and its location near the gas stove leads one to conclude it must have been used for …
This is the first in a series of articles on electrifying our house so we can “stop burning stuff.” Yes, we already have electricity, but we use fossil gas for heat, hot water, and cooking. That’s what we plan to electrify, eliminating fossil gas from our home. Our gas is provided by PG&E (Pacific Gas & Electric Co.), our notorious utility company. Notorious because it killed eight people in San Bruno, California in a massive gas explosion in 2010 then they followed that up by killing another 85 people by starting the Camp Fire in 2018. In 2020 the company filed for bankruptcy, and since then been resuscitated. However, to its customers it’s still the same old PG&E.
Historian Robert Righter and others have noted that the diameter of Charles Brush’s wind dynamo was 56 feet or about 17 meters in diameter.[1] However, a question has arisen over whether this is accurate or not. The question arises from the famous photo of a man mowing the lawn near …
Stopping to charge your EV on a road trip may seem an inconvenience to some, but not to us. True, charging takes longer than filling up with gasoline in a gasser. But we’ve learned to turn the longer EV refueling stop to our advantage. We get out, stretch our legs, …

When China starts scaling a technology at massive levels, the rest of the world should take notice. That’s not a geopolitical statement, it’s a thermodynamic and logistical one. China doesn’t mess around when it comes to heat, power, and infrastructure. And in the case of ground-source heat pumps used for district heating, China has been quietly laying down tens of thousands of systems, with over 77 GW of installed capacity by 2019.
t’s unclear what geothermal’s path forward is outside of conventional geothermal where it’s viable and heating and cooling provision with heat pumps. The capital costs of the unconventional forms mean they have to run at 90% capacity factors. While they might technically be able to be load following in the future, that’s not something that they will be able afford to do. They have to compete with much cheaper batteries for grid firming in any event, and natural gas peakers can’t do that any more, as California along with a lot of other jurisdictions are demonstrating. They can’t be built on the same footprints as coal plants and get anywhere near the GW scale capacity, so can’t claim effective reuse of boilers, turbines and transmission assets that are left behind.
Conventional geothermal electrical generation, where conditions are right, is an excellent form of renewable generation. It keeps chugging along day and night, offering firmed power with some of the highest capacity factors in the business and very low emissions per MWh. Yet, despite its many advantages, geothermal often gets left out of the clean energy conversation. Let’s dig into this a bit.
Historically, geothermal energy has been repeatedly touted as the renewable savior — clean, reliable, and providing essential baseload power right beneath our feet. However, despite periodic waves of excitement, actual global growth has been modest at best. As the current wave of enthusiasm builds, it’s prudent to ask: will this geothermal revival finally deliver, or is history poised to repeat itself?
By contrast the IEA grossly underestimated increases in renewable energy generation. As can be seen in the Figure 1 below, reproduced from a recently published academic paper the IEA has had a consistent habit of projecting much smaller increases in world solar PV generation than has happened in practice. The vertical axis represents annual solar PV additions in GW. The IEA projections consistently have solar pv capacity more or less levelling off in the future, whereas in reality there has been exponential growth of the technology.
The following pages include some of the photos from my collection, including both digital and scanned images.
My photographs have appeared in Popular Science, Sierra, Solar Age, Alternative Sources of Energy, L’Espresso, Air & Space Smithsonian, Windpower Monthly, WindStats, Renewable Energy World, and other magazines, in several engineering and physics textbooks, on brochures and posters published by the National Renewable Energy Laboratory, by Friends of the Earth (UK), by the Union of Concerned Scientists, and the World Wildlife Fund.
