Renewable energy is growing faster than most forecasters expected, and this is the biggest category on the site. Our posts gather the evidence: electricity systems in the USA, China and many other countries going renewable rapidly, studies suggesting well over 100 countries could reach 100 percent renewable energy within years, and debates about how reliable the estimates are. We also keep an eye on forecasting failures, because agencies have repeatedly underestimated solar.
Solar and wind are the headline technologies. Posts look at booming photovoltaic supply, thin film and perovskite efficiency gains, concentrated solar, falling wind prices, offshore wind, wave and tidal power, geothermal and the carbon footprint of wind turbines. Others tackle myths, such as whether wind turbines kill birds, whether solar panels create a waste problem, and how recycling really works.
The category also covers the practical side of the transition: inertia in electricity grids, off-grid and uninterruptible power, heat pumps, balcony solar for renters, who owns Australia’s electricity and grid, and what green energy can save a household each year. A recurring theme is that stopping the burning of fossil fuels is simpler than it sounds, because wires carry energy more efficiently than pipes. Start here for the facts behind the energy transition.

The 2026 World Nuclear Industry Status Report confirms a quarter-century of stagnation: 411 reactors, record 375 GW, yet just 8.8% of global electricity. Russia and China dominate reactor construction, AUKUS partners the UK and US run ageing fleets, and renewables added 462 times more new capacity than nuclear in 2025.
Oil wells average just 15 years of life, stretching to 25–30 years only with heavy maintenance. Solar panels need almost no upkeep, run for at least 30 years, and can be 80–95% recycled at end of life. So why do people whine about solar panels and not about oil derricks?
Australia’s EV sales more than doubled in the first half of 2026. The Electric Vehicle Council’s tenth State of EVs report shows 157,957 new EVs sold, a 25.8% share of new-car sales by June and 196 models on offer. However, electric trucks, vans and several state governments still lag behind.
The evidence is in: new solar and wind now undercut every fossil fuel option on cost, EVs catch fire 10–20 times less often than petrol cars, and the UK Treasury’s own numbers show that not transitioning costs twice as much as doing it.
A detailed look at solar panel recycling. The egulators are aware and have pilot programs in place and ready to scale for up to ensure the tsunami of panels from 2030 can be recycled. A challenge is cost and over 80% are currently landfilled. By 2030 with right policies that can be brought up to over 60% or higher.
Solar panels can be recycled. To date, there has been no legal requirement to do so, but governments are now mandating and the purchase price will includee recycling costs. The latest innovation is to recycle 98% profitably with recovery of all components and even recycling of silicon and glass, rather than repurpose.
Geothermal energy, although currently contributing less than 1% to global energy production, has the potential to supply 140 times the world’s energy demand. Next-generation geothermal, including engineered, advanced, and hybrid systems, can be used for heating, cooling, and power generation . Scaling geothermal requires leveraging the oil and gas industry’s expertise and infrastructure.
Renewable energy produced locally regains sovereignty when fossil fuel is gone. Countries regain sovereignty when they no longer have to buy their energy from fossil fuel rich countries. Fossil fuel exports provide luxury for about 24 countries – the rest of the 160 countries are dependent on importing oil gas and coal.
Inertia in electricity grids is a term used in electricity grids describing the behaviour of voltage. Many think solar and […]
Wartsilar, better known for shipping engines in their modelling says 98% net zero by 2050 is cheaper than 100% WWS by Prof Jacobson. Meanwhile 100% is possible says Prof Mark Jacobson.
RethinkiX says Stellar enegy – 500% is most cost effective for superabundant energy.
Wartsilar fails the fossil fuel argument and keeps about 12,000 TWh of generation in the mix – albeit for just 3% of the electricity generation. The world demands 100% zero emissions, not net zero.
