News & Articles on Solar Energy
While I have primarily worked with wind energy, I have long been a proponent of renewable energy in the broadest sense. This includes solar energy. My work in Canada, especially Ontario, stressed inclusion of solar energy because it had been previously overlooked. At one time Ontario was one of the leading jurisdictions in North America developing solar photovoltaics due in part to the programs I and others pushed. The political winds changed and these policies were abandoned and with it Ontario’s progress toward a renewable energy future.
Two stories: Denmark’s soaring renewable success and global nuclear construction disaster

Renewables will make up more than of Danish 100% electricity in a couple of years time and just wind and solar not long after that. On the other hand a new study concludes that, around the world, nuclear power projects have cost overruns that are over 100%. Solar and wind have very low, if any cost overruns.
Renewables provided over 90 per cent of the world’s increase in generation capacity in 2024. How is this happening?
By
David Toke
Solar and wind power are dominating new generation capacity around the world. This is to such an extent that, according to data from the International Renewable Energy Association (IRENA), 90 percent of the net increase in global electricity generation capacity came from wind or solar and 93 percent from renewable energy as a whole. Solar PV provided the lion’s share of this increase, at 72 percent, with wind providing 18 percent, fossil fuels 7 percent, hydro 2 percent, bioenergy 1 percent, and nuclear power less than 0.5 percent.
How the IEA is grossly biased against renewables – the IEA should be scrapped
By
David Toke
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.
How California’s Rooftop Solar Customers Benefit Other Ratepayers Financially to the Tune of $2.3 Billion

The California Public Utilities Commission’s (CPUC) Public Advocates Office (PAO) issued in August 2024 an analysis that purported to show current rooftop solar customers are causing a “cost shift” onto non-solar customers amounting to $8.5 billion in 2024. Unfortunately, this rather simplistic analysis started from an incorrect base and left out significant contributions, many of which are unique to rooftop solar, made to the utilities’ systems and benefitting all ratepayers. After incorporating this more accurate accounting of benefits, the data (presented in the chart above) shows that rooftop solar customers will in fact save other ratepayers approximately $2.3 billion in 2024.
New study shows how CA rooftop solar consumers save all ratepayers $2.3 billion

The utilities’ “cost shift” claim is promoted by a small group of seemingly independent utility allies in coordination with the major investor-owned utilities. These include organizations who should know better, but for one reason or another have chosen to align with the utilities: the Haas School of Business at Berkeley, Natural Resources Defense Council (NRDC), and The Utility Reform Network (TURN) But these groups simply repeat the fraudulent accounting methods used by the Public Advocates Office and other utility-captured groups, in many cases referring to each other in a circular pattern.
World Moving On Without USA As It Declines

Michael Barnard
The world will keep a weather eye on the thrashing giant. Those like me who once admired many things about the country will mourn the loss of more and more checks and balances, the erosion of good governance, the continued increase of grievances of the working and middle class which Trump, his successors, and other Republicans will continue to exploit. The neighboring countries of Mexico and Canada will catch colds as the elephant sneezes. But Europe, China, India, and the rest of the world will continue to move forward without the United States.
So how much of UK electricity could solar pv provide?
By
David Toke
Even in not-always-sunny UK solar pv could provide up to 40 per-cent of annual electricity production. That is without a significant amount of curtailment of production or even the need to convert the electricity into stored energy such as hydrogen. Of course this is dependent on there being enough provision of batteries. Solar plus batteries will be the dominant energy system in the world in future decades, but they will also be centrally important in UK.
Solar-Powered Vehicle Makes a Cannonball Run and Sets a New Record

On July 21, 2024, Will Jones, Kyle Samluk, Brett Cesar, and Danny Ezzo—four engineering students from Michigan with an EV built out of eight solar panels and three bicycle wheels—set a new record for making the run from Red Ball Garage in New York City to the Portofino Hotel in Redondo Beach—the famed start and finish of the Cannonball Run.
China building two-thirds of world’s wind and solar projects

The amount of wind and solar power under construction in China is now nearly twice as much as the rest of the world combined, a report has found. Research published on Thursday by Global Energy Monitor (GEM), an NGO, found that China has 180 gigawatts (GW) of utility-scale solar power under construction and 159GW of wind power. That brings the total of wind and solar power under construction to 339GW, well ahead of the 40GW under construction in the US.
