"You'll feel so much more confident in your clean-energy decisions." There are a thousand reasons for a homeowner to install solar panels, and just as many providers willing to do the work — but some are more reliable and cost-effective than others. The many options can be so confusing that some potential buyers give up before
Two recently released reports suggest lithium-ion EV and home batteries should stand the test of (warranty) time. Home Batteries: A Positive Sign Most home batteries come with a 10-year warranty these days, with a certain amount of battery capacity warranted at the end of the period – usually around 60% to 70%. This means at the end
A real-world range test has shown what distance a driver should expect to cover from a fully-charged battery on some of the latest electric vehicles (EVs). The most efficient new car in the test, conducted by What Car?, was the Tesla Model 3 RWD, which averaged 4.4 miles per kWh. The least efficient, the Audi
A special service of blessing for new solar panels is being held at a Grade I-listed church. Holy Trinity and St Mary, in Berwick-upon-Tweed, Northumberland, has installed 26 panels on a flat roof on the south side of the building. It is hoped they will provide 70% of the church's energy requirements. Susan Phillips, from
Solar’s extraordinary forecast-defying growth, explained. Every day, the sun’s rays send 173,000 terawatts of energy to Earth continuously, 10,000 times the amount used by all of humanity. Which is to say, the potential for solar energy is immense, and we’re nowhere near the limit. That’s why solar energy is such an
Exclusive: Reliance on fossil fuels fell in August to less than one-fifth of all electricity generated across country Great Britain’s electricity system has recorded its greenest ever summer after growing numbers of wind and solar farms cut the need for gas power plants to fresh lows. Analysis of energy generation data, commissioned by the Guardian,
It took eight years of field measurements for researchers at the RWTH Aachen University in Germany to estimate the usable capacity of home battery energy storage systems and develop a dataset covering 106 system years and 14 billion datapoints. Their key finding was that home battery systems lose about two to three percentage points of
Using physics and estimation to assess energy, growth, options—by Tom Murphy https://youtu.be/sPrBmM5qJGk MM #18: What Can I Do? This is the final installment in the Metastatic Modernity video series (see launch announcement), putting the meta-crisis in perspective as a cancerous disease afflicting humanity and the greater community of life on Earth. We have arrived at the part where people
Norway, one of the world's largest exporters of oil, now has more electric cars on its roads than petrol-driven vehicles. Of the 2.8 million private cars registered there, 754,303 are now all-electric, compared with 753,905 that run on petrol, according to new figures from the Norwegian Road Federation. The Nordic country of 5.5 million
Used EV sales are growing fast, with buyers attracted by second-hand value, improved battery longevity, low running costs and the way they drive Used car EV sales are growing faster than new EV sales right now and it’s easy to see why, since electric cars tend to lose their value pretty
