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.

Clean energy blowing in the wind

EDP Renewables has begun operations at its Sharp Hills wind farm 250 kilometres northeast of Calgary. Construction of the 300 megawatt project — approved by Rachel Notley’s NDP government — began in 2021. Each megawatt of capacity is costing $2 million at this $600 million facility. By comparison, a megawatt of capacity at Site C will cost about $18 million, if the 10-year long construction project is able to produce electricity in 2025.

BC energy policies based on myths and misinformation

Arguments claiming impracticability of wind and solar power integration in British Columbia never passed scrutiny. Elsewhere in the world, it has been happening rapidly. Days ago, BC NDP announced a new call for clean power. No important details were provided but it seems government will replicate the insider-friendly private power program favoured by BC Liberals. That resulted in commitments for power that lasted as long as 70 years at prices that have been multiples of market price. The province should not go that way again.

The downside of wind power

Unlike Site C in British Columbia, wind projects have relatively low budgets and short construction timelines. Those factors impede privatization of public wealth. While good for consumers of electricity, low-cost generating facilities offer only short-term benefits to those who build them.

Winds of change

Although humans have harnessed wind energy for 1,400 years or more, global capacity only began to grow substantially in the 21st century. Growth is a fraction of that needed if Earth is to achieve net-zero carbon before climate disaster overtakes humanity. Wind energy is affordable. Wind prices for power contracts signed in the last few years are 1.5–4 cents per kilowatt-hour. Compare to Site C where electricity will cost between 15 and 18 cents per kilowatt-hour.

Wind turbine for when the winds don’t blow

Years ago, the head of BC Hydro said the least-cost solutions to energy needs were conservation and efficiency. While that remains true, recovery of energy now wasted would be advantageous. Alpha 311 now offers a vertical axis wind turbine that can produce electricity by harvesting energy produced by moving vehicles.

Next generation wind energy

Those of us who opposed construction of the Site C dam—including the BC NDP until May 2017—argued that rapid advances in alternative energy systems meant flooding the Peace River valley was inappropriate and unnecessary. That was true in 2017 and remains true today…
