Solar roadways have been promoted as a way to fight climate change, put people to work and make driving safer. But on closer inspection the reality is less than impressive.
Lithium batteries offer renewable energy electricity power storage.
High quality Li-ion batteries could help Africa optimise renewable energy.

Environmentalists and climate hawks are cheering, but many experts aren't excited about the state making rooftop solar panels mandatory on most new homes beginning in 2020.
Annual water requirements of a PHES-supported 100% renewable electricity grid would be much less than the current fossil fuel system, because wind and PV do not require cooling water.

What's at stake as the Trump administration imposes trade sanctions on imported solar panels? A look at the US solar energy industry, which generates more than twice as many jobs as coal energy.
Senegal has the highest rate of electricity access among Africa’s less developed countries.
To achieve universal energy access by 2030, the UN says Senegal must double its electrification rate.
Diatoms - like those seen under a microscope here - can teach us a lot about harvesting light.
Diatoms' tricks may offer new insights that keep solar cell energy running efficiently and robustly throughout their processes.
Kenya needs to expand its energy transmission network which is plagued by flaws dating back decades.
Kenya's inadequate electricity supply is due to an over-reliance on hydropower, high energy and infrastructure costs.
Cape Verde’s renewable energy resources account for about 25% of total energy production.
With cutting-edge technologies and innovative business practices, Cape Verde can achieve its goal in a way that is cost-effective and equitable
The price of new-build renewable energy is expected to fall significantly relative to new-build coal energy in coming years.

Fossil fuel advocates claim only coal and gas can deliver cheap and reliable energy, and renewables are synonymous with sustainability. But demand management can solve all three problems.
Ecologically sound housing needs to be built on a much larger scale.
Solar subsidies encouraged a massive take-up of solar panels in Australia.

Now that our rooftop solar industry has matured, we need to reconsider the purpose of feed-in tariffs and align them with our goals for the electricity system in the future.
The Inga dams in the DRC generate about 1000 MW of electricity for the country.
Small-scale renewable energy projects have tremendous potential to power rural areas in the DRC. Rural areas in the country have very little access to electricity.
