Your monthly roundup of good news for the climate
Dear Catherine,
Another month of breakthroughs, sustainability-seeking solutions and
transformative progress!
Researchers have discovered a new, efficient technique to extract lithium
from seawater, groundwater and wastewater, reducing the environmental
impact of battery production. Solar energy technology can now generate the
extreme heat required for manufacturing steel and cement. Investment in
renewable energy is set to reach a whopping US$2 trillion this year,
surpassing fossil fuel spending. And seven countries are generating all
their electricity from renewables.
Let's embrace each advancement — no matter how small — as we journey
together toward a brighter future.
We’ll talk to you soon,
The David Suzuki Foundation

A better way to get lithium for batteries
A big issue with renewable energy is that the batteries used to store it
often use lithium, and extracting lithium from brine pools and mining comes
with environmental costs. Now, researchers from the University of Chicago
Pritzker School of Molecular Engineering have found an efficient way to
extract lithium from common sources such as seawater, groundwater and
wastewater using an electrochemical process.

Harnessing the sun for steel and cement
It takes a lot of heat, mostly from fossil fuels, to manufacture steel,
glass, ceramics and cement — which accounts for about 25 per cent of global
energy consumption. Scientists in Zurich, Switzerland, have now found a way
to use synthetic quartz to trap heat from the sun at temperatures exceeding
1,000 C. Previously, solar heat could only be trapped up to about 170 C.
The much higher heat can be used to smelt steel and cook cement.

Renewable energy keeps on booming
Renewable energy investment is expected to reach US$2 trillion this year,
double the amount going to coal, oil and gas, according to the
International Energy Agency. “The rise in clean energy spending is
underpinned by strong economics, continued cost reductions and by
considerations of energy security,” IEA executive director Fatih Birol
said.

Many countries switching to clean power
Seven countries are generating all their energy from renewable sources.
According to *EuroNews*, “More than 99.7 per cent of electricity in
Albania, Bhutan, Ethiopia, Iceland, Nepal, Paraguay and the Democratic
Republic of Congo comes from geothermal, hydro, solar or wind power.”
Norway got more than 98 per cent of its energy from renewable sources and,
“Another 40 countries got at least half of their electricity from
renewables in 2021 and 2022 including 11 in Europe. Others, like Germany or
Portugal, are capable of running on 100 per cent wind, water and solar for
short amounts of time.”
