Ending fossil fuels benefits all

Many people in Canada are employed in fossil fuel industries. Were production of carbon-laden, climate damaging products to decline or end, many towns would be disrupted. However, quality of life would improve since toxic contaminants are by-products of oil, gas, and coal production. Overall employment would increase and stable populations would lead to safer communities…

Batteries…

Large reductions in the cost of renewable technologies such as solar and wind have made them cost-competitive with fossil fuels. But to balance these intermittent sources and electrify our transport systems, we also need low-cost energy storage. Lithium-ion batteries are the most commonly used. Lithium-ion battery cells have also seen an impressive price reduction. Since 1991, prices have fallen by around 97%. Prices fall by an average of 19% for every doubling of capacity. Even more promising is that this rate of reduction does not yet appear to be slowing down.

Clean energy solutions

In 2017, Site C proponents said the dam was required because British Columbia needed dispatchable electricity. According to those keen on the megaproject, low-cost wind and solar power could not be integrated into BC Hydro’s systems. At the time, 97.5 percent of the utility’s generating capacity was hydro. Like batteries, reservoirs store potential energy. When consumers use electricity from wind and solar sources, hydropower utilities keep water behind dams, ready for use when needed…

Renewables are the key to low emissions, but…

Proponents of hydroelectric dams love to talk about these as low-impact sources of clean energy. Many proponents expect to gain financially from construction of the megaprojects. To them, self-interest is always more important than public-interest. But many of the proponents expect to gain financially from construction of the megaprojects. To them, self-interest is always more important than public-interest. In British Columbia, the financial cost of electricity from Site C will be 4x to 6x that of wind and solar alternatives. Authorities choose to disregard human and environmental costs and leave them unmeasured.

Plug pulled on PowerBC

The item below the separator was published in March 2018. That was three years before the Site C budget doubled to $16 billion, and we’ve now entered the fourth year since the dam budget was publicly updated. While overall inflation in Canada has been about 16% during the past four years, the non-residential construction industry experienced historic levels of inflation in 2022 and 2023. No one should be surprised when after the October 2024 provincial election, the Site C budget is revealed to be above $20 billion.

Energy politics in BC

The U.S. Department of Energy (DOE) reported that wind and solar accounted for 71 percent of U.S. electric-power capacity additions in 2022. 8.5 GW of wind power capacity was added for investments totalling C$16 billion. By comparison, Site C will cost at least C$16 billion and provide 1.1 GW of power capacity. However, the budget for the project near Fort St. John has not been updated for three years…

For Site C promoters and enthusiasts

Climate change is one of the most pressing global issue in contemporary times, and dams play a substantial role in aggravating it by becoming feeding grounds for methane-producing microbes. In addition, dams fragment rivers and disrupt their natural flow, threatening the survival of aquatic fauna, especially migratory species. Dams are also culpable for disrupting the biogeochemical cycles of river ecosystems, thereby impacting their function and structure. Taking all the environmental impacts of dams into account, the apparent economic gain from them may not be worth it…

You couldn’t stop solar if you wanted to stop solar

Worldwide solar energy capacity has been growing rapidly. In 2022, it was 150 times higher than in 2006 and more than double the level of 2018 when BC Hydro moved to discourage solar power systems. A tiny proportion of the utility’s accounts was feeding solar power to the grid, but BC Hydro worried about added customers embracing solar, particularly large consumers of electricity…

If we have the will, energy solutions are within reach

Methods of creating or capturing energy near demand points are gaining prominence and threatening the disruption of today’s giant utilities. A paper from Germany’s Karlsruhe Institute of Technology suggests millions of buildings can be energy self-sufficient with solar power, retrofitting, energy storage systems, and heat pumps. Many single family homes could abandon the electrical grid unless owners stayed connected to sell excess power to utilities.

Super cheap electricity

Seattle based writer David Roberts reports on energy matters. Recently Roberts explored the variability of renewable energy. Opponents of wind and solar power rely on this subject to raise objections. Despite virtually all of the electricity generated by BC Hydro being dispatchable, the public utility has discouraged addition of variable renewable energy (VRE).

Boundless, scalable, clean energy

Decarbonization is a catchword used by the fossil fuel and nuclear power industries. But those groups cannot eliminate inherent dangers. Unless we develop safe, carbon-free energy sources, we cannot sustain current standards of living. And, perhaps we cannot sustain human life in the long-term. But, as billions of public dollars pour into subsidies of dangerous energy sources, promising technologies seem to get minimal support from governments…

Community-powered energy

Over the years, clean renewable power costs have decreased steadily and efficiencies have improved. The British Columbia government and the main public utility offer few incentives for creation of energy near to points of consumption. Green electricity must displace fossil fuels but the NDP allows BC Hydro to maintain its near monopoly while it discourages local cooperatives seeking to create power for self-consumption. Provincial decision makers cling to business models rooted in the 1960s.

Carbon-free, non-destructive energy

A pumped-storage hydroelectricity (PSH) facility moves water into a high-level reservoir during times of low demand, and then generates electricity by releasing water during times of high demand. Most storage occurs at night and most electricity is generated during the day. PSH is a proven method of energy storage with competitive round-trip efficiency and long life spans.
