Hydropower damages river systems in Africa: How more solar and wind power can solve this problem

TechXplore

Across the African continent, more than 300 new hydropower projects are planned to meet the growing demand for electricity. Another looming problem with hydropower is that the water cycle is affected by climate change. Some of these will require big dams, which can have major negative environmental impacts.

California Renewable Curtailments Surge as Coronavirus Cuts Demand

GreenTechMedia

California grid operator CAISO has been curtailing renewable energy at record levels this year, as the state’s ever-rising share of solar power during daylight hours increasingly outpaces electricity demand. Adding to its challenges, the grid operator is now contending with falling power demand caused by the coronavirus pandemic.

The swansong of African hydropower?

Envirotec Magazine

Hydropower, traditionally one of Africa’s most important sources of electricity, will rapidly fade in importance and cede its position to solar power. For decades, many African countries have relied on hydropower for electricity generation, including projects that inspire as much awe as controversy.

What happens after your country runs on 99 percent renewable electricity?

The Verge: Energy

In the winter, like a six-month period from June to December, many of the hydropower plants get surplus flows. That’s when we have low wind, but we have more hydropower. Why does Costa Rica rely so heavily on hydropower, which makes up 73 percent of electricity generation? So, it will be affected.

New York?s Energy Transition (and Challenges) in 5 Charts

GreenTechMedia

That leaves a massive gap to be filled by clean energy, since more than half of the state’s carbon-free emissions today come from nuclear power, as shown in the chart below. Larger-scale transmission projects aimed at carrying Canadian hydropower and wind power downstate, such as the $2.2 Source: NYISO.

More wind and solar capacity could save some of the world’s most important rivers

Renewable Energy World

This dramatic expansion of wind and solar has been driven by precipitously falling costs. The cost of new wind and solar generation, on a levelized cost of energy basis, is now lower than that of new thermal and hydropower generation, and increasingly below the operating cost of existing thermal plants.

If the U.S. and China can agree on renewables, surely our provinces can do the same

Clean Energy Canada

And yet it would be a mistake to view renewables as an active battleground in the culture wars, losing sight of their real value as key technologies that can deliver low-cost electricity at a time when demand is growing. and Ontario have started advertising near-term procurements focused on new wind and solar resources. And both B.C.
