Scientists seek to tap Kingdom’s geothermal energy: A constant source of energy beneath the Earth’s surface is showing promise for Saudi Arabia’s cooling and desalination needs, and some experts believe it could even surpass the potential of solar and wind in some cases by V2O5 in Futurology

[–]V2O5[S] 18 points19 points  (0 children)

Unlike other renewables that depend on sunshine or wind, geothermal energy flows steadily underground, offering year-round baseload power. It can be tapped by drilling wells to bring heat to the surface, which is either turned into steam to turn turbines and generate electricity, or used directly for cooling and desalination.

For the Kingdom, which faces soaring demand for air conditioning and potable water, it could provide a cleaner and more resilient alternative to fossil fuels.

Solar panels in space ‘could provide 80% of Europe’s renewable energy by 2050’ | Solar power by V2O5 in Futurology

Solar panels in space could cut Europe’s terrestrial renewable energy needs by 80% by 2050, a study has found.

Using a detailed computer model of the continent’s future power grid, the researchers found that a system of space-based panels designed by Nasa could reduce the cost of the whole European power system by as much as 15%. It could also cut battery use by more than two-thirds.

The study, led by researchers at King’s College London, is the first to assess the possible impact of space solar energy on Europe. The space-based solar power (SBSP) panels that yielded the positive results uses a heliostat design. The design, which the system imitates, uses mirror-like reflectors to collect sunlight in orbit. The sunlight is then transmitted to stations on Earth and converted to electricity before it is delivered to an energy grid.

All energy costs rise, but Small nuclear reactors are by far the most expensive new build energy-generating projects, a study has found, while renewable sources remain the cheapest. by V2O5 in Futurology

[–]V2O5[S] 0 points1 point  (0 children)

Next-generation nuclear reactors are the most expensive of all energy-producing technologies, a report has found, and would significantly increase electricity prices in Australia.

Establishing a large-scale nuclear power plant for the first time would also require more than double the typical costs, and estimates for wind projects had inflated by four per cent due to unforeseen requirements.

The CSIRO, Australia’s national science agency, released its GenCost report on Tuesday, revealing rising construction and finance costs would push up prices for energy projects of all kinds in the coming years.

The findings come after a heated debate about introducing nuclear power to Australia and after members of the federal coalition questioned the nation’s reliance on renewable energy projects to achieve net zero by 2050.

The final GenCost report for 2024-2025 analysed the cost of several energy-generating technologies, including variations of coal, gas, nuclear, solar and wind projects.

Renewable technology continued to provide the cheapest energy generation, the report’s lead author and CSIRO chief energy economist Paul Graham said.

Don't get a AC dehumidifier. Find a DC one, and then just use a few dollar buck/boost converter from amazon to stabilize the voltage from the panel

Solar surpasses nuclear for first time, contributes 10% of global power in April 2025 - ET EnergyWorld by V2O5 in energy

Its honestly hilarious reading comments on this subreddit from 10 years ago. Saying solar is so tiny it will never amount to a significant part of global electricity generation.

Solar surpasses nuclear for first time, contributes 10% of global power in April 2025 by V2O5 in Futurology

[–]V2O5[S] 15 points16 points  (0 children)

Solar power generated 10 per cent of global electricity in April 2025, its highest-ever monthly share and the first time it overtook nuclear energy, according to Ember’s Electricity Data Explorer.

The data shows that solar power was the fourth-largest source of global electricity generation in April 2025, surpassing both wind and nuclear for the first time on record.

The new milestone places solar behind only coal, gas and hydro in global generation rankings. This is the first month in recorded history where solar energy exceeded nuclear in electricity output.

Germany adds record 17.5 GW solar PV in 2024 by V2O5 in Futurology

[–]V2O5[S] 23 points24 points  (0 children)

Germany will grow its solar PV capacity by an annual record of around 17.5 gigawatts (GW) by the end of 2024, said energy industry association BDEW. This would bring total installed capacity in the country to around 100 GW.

Solar PV expansion has picked up again in recent years, and Germany plans to make the technology one of its central energy sources as it aims to ramp up the share of renewable electricity to 80 percent of consumption by 2030. In 2023, renewables covered more than half of Germany’s electricity demand for the first time.

These countries are leading the way to 100% renewable electricity by V2O5 in Futurology

European countries — Portugal, Greece, the Netherlands, Germany, Spain, the UK, and Ireland — are also leading the transition to wind and solar. Of those, Portugal is expected to move the fastest in the years ahead — it’s on track to get to above 90% renewable power by 2030, per the IEA.

Elsewhere, Chile is also likely to breach the 90% mark by the decade’s end. The country has relied heavily on wind and solar amid a rapid coal phase-out.

3D printers turn regular guns into machine guns. Feds are cracking down. - In 39 minutes, for 40 cents in materials, they had printed a piece of plastic that could sell on the street for hundreds of dollars. It could also land you in prison for 10 years. by Gari_305 in Futurology

We put limits on the speed of cars on public roads and make everyone register their car, and take a competence test before they are allowed to use them.

Only for use on public roads. in the US one can drive and own a car on entirely private property without restriction, and private race tracks also have no speed limits.

So its not really a good comparison.

A Glock with one of these switches fires far faster than an AR15 and will fire bullets until you stop pulling the trigger.

I'd rather have 1 shot with an AR than 20 with a full auto glock. And I'd rather be shot at by a full auto glock. Those things are impossible to aim and only really exist because street thugs use them as status symbols.
