We have all the technologies needed to make the electric grid run on renewables and lower pollution. What are they and what are the barriers to adopting them widely?
Power failure. It’s gas, not wind, that’s pushing up electricity prices.
An eight year study of half hourly prices finds that wind and solar generation have been pushing wholesale electricity prices down.

Twelve power projects are in the running for federal government dollars: six pumped hydro, five gas and one coal. It's clear which one shouldn't be on the list, for economic and environmental reasons.
The world’s biggest thermosolar power complex is in Morocco.
Climate justice policies could potentially double as tools of colonialism that harm people outside the US.

The case for pragmatism, not dogma.
Access to water – not electricity – can have larger gains for health and well-being.
Providing people with clean drinking water and sanitation is less expensive than grid electrification and it could improve more lives.
This roof in Newcastle has become the first in Australia to be covered with specially printed solar cells.

What if it were a lot easier to install solar power?
Silicon is cheap and a good semiconductor, but it's bulky and rigid. Using organic polymers as semiconductors could yield solar panels with the physical characteristics of plastics.
