Governments must expand the number of people who see themselves as “winners” in the transition to a low-carbon society.
A significant number of African countries might not make a decisive leap to renewables this decade.
The transition to 100% renewable energy will require a lot of land – mostly in regional Australia. This presents big challenges, and opportunities, for the farming sector.
With Indonesia’s huge internet users, crowdfunding can be used to get funding faster for renewable energy projects.
Last year, renewables provided a whopping 60% of South Australia’s electricity supplies. The remarkable progress came as national climate policy was gripped by paralysis – so how did it happen?
The weather-related impacts of climate change will increasingly threaten critical infrastructure in the future. Shifting electricity grids towards microgrids could help.
The unprecedented intensity of two summers of bushfires, first in the east and then in the west, offered harsh lessons for Australians. One is that some settlements must retreat from high-risk areas.
Heat waves, droughts and deep freezes can all strain the electric grid, leading utilities to impose rolling blackouts. Climate change is likely to make these events more common.
Investment in renewable electricity needs bipartisan political support and some bold decisions if New Zealand is to meet its future energy commitments.
In a bid to ditch fossil fuels, some countries are considering carpeting deserts with solar panels.
Emissions from road transport in New Zealand have doubled since 1990, and the Climate Change Commission recommends sweeping changes to switch to electric transport options.
Replacing fluorescent lights with efficient LED alternatives is the single best way to cut schools’ electricity costs.
Per capita electricity use was higher in the 1970s than today.
Ramping up fossil power sources is no longer a good option in an energy-supply crisis. Bring in the weather forecasters.
Companies are using these credits to offset their emissions, though many projects won’t meaningfully reduce carbon in the atmosphere.
The end of coal-fired generation in Australia is inevitable. But the federal government can do more to ensure an orderly transition to renewables – avoiding price spikes and supporting workers.
Weak regulation and a lack of mandatory inspections have increased fire risks for the one in four homes with rooftop PV panels. Here’s what we need to do to be safer.
The latest estimates of electricity generation costs in Australia find renewables will soon be the cheapest even with grid integration expenses.
Australia’s biggest states are taking back control of their electricity systems, because the way we make power is changing.
