With its abundant sunshine and unique topography, Indonesia is able to generate 100% green electricity from its solar energy by 2050.
Solar films could turn windows into powerful solar panels.
New lightweight, efficient and ultra-thin solar technologies show promise, but it may be too soon to abandon conventional solar photovoltaics.
The costs of renewable energy, including solar photovoltaics, is declining rapidly.
Investing billions in refurbishing nuclear generating stations doesn't make economic sense as the cost of renewables fall dramatically.
Large scale wind farms are driving Australia’s renewable energy generation.

Australia is installing renewable energy at more than ten times the global average. This is excellent news, but raises serious questions about integrating this electricity into our grids.
An all-renewable grid will mean more electricity and more transmission lines.

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?
Rooftop solar has boomed, but soalr panels only last about 20 years. What happens to the waste?
Australia urgently needs to prepare for a coming tsunami of solar panel and battery waste.
Almost 80 million Nigerians do not have access to electricity and its erratic supply is costing the economy an estimated $29 billion annually. Nigeria's abundant sunlight could be the solution.
Expanding solar power potential more than it’s needed could replace more expensive energy storage.
Solar and wind can't deliver power on demand. But overbuilding solar and wind, and simply dumping unneeded energy, would go a long way to smoothing out those bumps, study finds.
Energy Minister Angus Taylor has six pumped hydro projects on his list, and most are better taxpayer investments than the already announced Snowy 2.0 project.

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.
More spin less gas?
The choice is now between a green grid or a whole lot more gas-fired power.
The Mugga Lane Solar Farm in the ACT is part of a new wave of large-scale renewable energy projects.

Australia could be getting half of its electricity from renewable energy by 2025, even without government subsidies for new wind and solar projects, according to a new analysis of energy industry trends.

Scientists have modelled the effects of huge hypothetical energy projects in the desert.
Many rural communities across Africa have dropped kerosene lighting for various electrical lights.
A lighting revolution is underway across Africa that's occurred largely without government or donor involvement.
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.

The first commercial-scale installation of rooftop solar cells, printed with specialised inks, is a step towards an energy future in which solar power can be stuck to any roof or structure.
The number of coal mining jobs has gone up slightly, but many times less than solar-related ones.

The Trump administration's Affordable Clean Energy Plan would help the declining coal industry, but a study shows many coal workers could transition to a new industry – solar – and earn more money.
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.
As the name suggests, Windy Hill near Cairns gets its fair share of power-generating weather.

There are calls from the backbench and elsewhere for the federal government to safeguard the future of coal. But do those calls make economic sense? A look at Queensland's energy landscape suggests not.
Nigeria has abundant energy resources but about 40% of the population don’t have access to electricity.
Nigeria can make some changes to harness its energy resources and lower its carbon footprint while providing power to its people.
The latest research suggests that in Australia, rooftop solar photovoltaics are more likely to be adopted by middle-class households.
Households that are most likely to go solar are those that can afford solar panels, but aren't so rich that they don't have to worry about their electricity bill at all, says a survey of 8,000 homes.
