Wind and solar on Thursday Island
Wind and solar on Thursday Island While rummaging around the internet to see if I could find any information on the performance of wind farms in Queensland (and especially in Far North Queensland – Andrew Blakers’ supposed panacea for the rather more correlated wind farm outputs in the NEM area), I came across Thursday Island, […]
In Maria’s Wake, Could Puerto Rico Go Totally Green?
In Maria’s Wake, Could Puerto Rico Go Totally Green? The ecological and humanitarian destruction of Puerto Rico has left the world aghast. But there is a hopeful green-powered opportunity in this disaster that could vastly improve the island’s future while offering the world a critical showcase for a sane energy future. By all accounts Hurricane […]

GOING OFF THE GRID TO COST OTHERS Victorian power company AusNet Services is sharing evidence of parliamentary pushing to update the industry that is ever-changing and incredibly innovative. AusNet is one of the five distributing companies of electricity in Victoria and covers the outer northern and eastern suburbs, as well as the eastern portion of […]
In Florida, You Can’t Use Your Own Solar Panels in a Crisis
In Florida, You Can’t Use Your Own Solar Panels in a Crisis When it comes to the U.S. economy, the “con” part offers the best description of the current relationship between business, government and the preyed upon consumer. The way things work in early 21st century America is large businesses bribe politicians in a variety […]
Is The Sun Setting On The Solar Boom?
Is The Sun Setting On The Solar Boom? The U.S. solar industry is expected to see its expansion significantly curtailed this year after installing record capacity in 2016, marking the first annual decline in installations for the industry. A new report from GTM Research and the Solar Energy Industries Association (SEIA) raises some question marks […]
How (Not) to Run a Modern Society on Solar and Wind Power Alone
How (Not) to Run a Modern Society on Solar and Wind Power Alone While the potential of wind and solar energy is more than sufficient to supply the electricity demand of industrial societies, these resources are only available intermittently. To ensure that supply always meets demand, a renewable power grid needs an oversized power generation […]
The “Wind and Solar Will Save Us” Delusion
The “Wind and Solar Will Save Us” Delusion The “Wind and Solar Will Save Us” story is based on a long list of misunderstandings and apples to oranges comparisons. Somehow, people seem to believe that our economy of 7.5 billion people can get along with a very short list of energy supplies. This short list will […]
A Possible “EMP” Hit On A Solar Power System — And How To Reduce The Risk
A Possible “EMP” Hit On A Solar Power System — And How To Reduce The Risk EMP is just a super-duper version of regular old radio frequency interference. With enough signal strength to blast past the reverse voltage limits of most semiconductors, an EMP attack is expected to destroy many solid-state radios, computers, controllers, etc. I […]
The real EROI of photovoltaic systems: professor Hall weighs in.
The real EROI of photovoltaic systems: professor Hall weighs in. The EROI of our various energy options, and its associated issues, may be the most important issues that will face future civilizations. The present discussion tends to vacillate between people who accept (or advocate) very high EROIs for solar vs people who accept (or advocate) […]
How to Get Your Apartment Off the Grid
How to Get Your Apartment Off the Grid Picture: Low-tech Magazine’s solar powered office. The typical solar PV power installation requires access to a private roof and a big budget. However, wouldn’t it be possible to get around these obstacles by installing small solar panels on window sills and balconies, connected to a low-voltage direct […]
As Drought Grips South Africa, A Conflict Over Water and Coal
As Drought Grips South Africa, A Conflict Over Water and Coal Facing one of the worst droughts in memory, South Africa’s leaders have doubled down on their support of the water-intensive coal industry. But clean energy advocates say the smartest move would be to back the country’s burgeoning wind and solar power sectors. Until a ferocious […]
Solar on the roof taxed as income
Solar on the roof taxed as income But the cost of a solar system can be written off over a period of years The solar panels on Mike Brigham’s roof in Toronto allow him to sell power back to the grid. He says solar provides power when Ontario most needs it — when the sun […]
Are Solar Panels Lifespans As Long As Industry Claims?
Are Solar Panels Lifespans As Long As Industry Claims? The success of solar has really been a case of successful innovations in financing as much as successful innovations in technology. As with some many other major capital expenditures consumers have traditionally had a hard time paying for rooftop solar systems up front. With system costs […]
