Green hydrogen produced using New Zealand’s mostly renewable electricity sounds like a great idea, but a high-tech smart rail and urban tram network is a more obvious and sustainable option.
Yallourn power station, Australia’s oldest and dirtiest coal plant, will close four years ahead of schedule. Without a national policy, coal workers are left dangerously exposed.
For an orderly transition from fossil fuels, Australia needs a carbon price to replace its hodgepodge of clumsy government interventions.
New social housing can provide a safe, secure and climate resilient home for tenants.
Wind turbines in cold areas typically include methods for removing and repelling ice, but those methods can waste energy. There’s a better way.
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.
