Solar power reaches 1 TW milestone

Posted by in categories: business, finance, solar power, sustainability, transportation

Like electric vehicles – traditionally seen as expensive and niche – solar power is now becoming a realistic option for many households, as well as businesses wishing to decarbonise their operations. While the upfront costs of installing a photovoltaic (PV) rooftop system can be expensive, home solar will usually pay for itself within 5–10 years – and then provides the owner with an essentially free, limitless supply of clean energy, decentralised and unaffected by price volatility. Unlike the world’s increasingly scarce, finite supplies of coal, oil and gas, our Sun will continue to shine for another five billion years. Home solar can also be combined with batteries (which, like solar, are rapidly declining in cost) for energy storage at night.

At the utility scale, gigantic solar projects are now emerging in many countries. Recent years have seen the first gigawatt-scale (GW) facilities. The largest has a nameplate capacity of 2.3 GW. China is the world leader, accounting for 30% of all solar electric generation, followed by Europe (21%) and then the USA (16%). The vast majority is produced from PV modules, with a small fraction obtained by concentrated solar power (using mirrors or lenses to concentrate a large area of sunlight onto a receiver).

It’s Official: NASA Confirms We’ve Found 5,000 Worlds Outside The Solar System

Posted by in categories: alien life, sustainability

In January 1992, two cosmic objects forever changed our galaxy.

For the first time, we had concrete evidence of extrasolar planets, or exoplanets, orbiting an alien star: two rocky worlds, whirling around a star 2,300 light-years away.

Quantum technology could make charging electric cars as fast as pumping gas

Posted by in categories: energy, quantum physics, sustainability

Whether it’s photovoltaics or fusion, sooner or later, human civilization must turn to renewable energies. This is deemed inevitable, considering the ever-growing energy demands of humanity and the finite nature of fossil fuels. Much research has been pursued in order to develop alternative sources of energy, most of which use electricity as the main energy carrier. The extensive R&D in renewables has been accompanied by gradual societal changes as the world adopted new products and devices running on renewables. The most striking change has been the rapid adoption of electric vehicles. While they were rarely seen on the roads even 10 years ago, now, millions of electric cars are being sold annually. The electric car market is one of the most rapidly growing sectors.

Unlike traditional cars, which derive from the combustion of hydrocarbon fuels, electric vehicles rely on batteries as the for their energy. For a long time, batteries had far lower energy density than those offered by hydrocarbons, which resulted in very low ranges of early electric vehicles. However, gradual improvement in eventually allowed the drive ranges of to be within acceptable levels in comparison to gasoline-burning cars. It is no understatement that the improvement in battery storage technology was one of the main technical bottlenecks that had to be solved in order to kickstart the current electric vehicle revolution.

However, despite the vast improvements in battery technology, today’s consumers of face another difficulty: slow battery charging speed. Currently, cars take about 10 hours to fully recharge at home. Even the fastest superchargers at the require up to 20 to 40 minutes to fully recharge the vehicles. This creates additional costs and inconvenience to the customers.

We’ve been hearing for years how nanotechnology is going to change the world. In movies and in headlines, nanotechnology is almost like “future magic” that will make the impossible possible. But how realistic are those predictions? And how close are we to seeing some of them come true? Let’s take a look at the state of nanotechnology.

New Quantum Technology To Make Charging Electric Cars As Fast as Pumping Gas

Posted by in categories: Elon Musk, energy, quantum physics, sustainability

Quantum charging will cut the charging time of electric vehicles from ten hours to three minutes.

Whether it’s photovoltaics or fusion, sooner or later, human civilization must turn to renewable energies. This is deemed inevitable considering the ever-growing energy demands of humanity and the finite nature of fossil fuels. As such, much research has been pursued in order to develop alternative sources of energy, most of which utilize electricity as the main energy carrier. The extensive R&D in renewables has been accompanied by gradual societal changes as the world adopted new products and devices running on renewables. The most striking change as of recently is the rapid adoption of electric vehicles. While they were hardly seen on the roads even 10 years ago, now millions of electric cars are being sold annually. The electric car market is one of the most rapidly growing sectors, and it helped propel Elon Musk to become the wealthiest man in the world.

Unlike traditional cars which derive energy from the combustion of hydrocarbon fuels, electric vehicles rely on batteries as the storage medium for their energy. For a long time, batteries had far lower energy density than those offered by hydrocarbons, which resulted in very low ranges of early electric vehicles. However, gradual improvement in battery technologies eventually allowed the drive ranges of electric cars to be within acceptable levels in comparison to gasoline-burning cars.

Sonoma County Airport Launches Solar Power Systems

Posted by in categories: climatology, government, solar power, sustainability

The Charles M. Schulz Sonoma County Airport had two solar power systems installed onsite and made them live in February. Over the course of their electricity-generating life spans, they will offset thousands of tons of CO2 emissions and potentially save millions of dollars.

Sonoma County has been hit particularly hard by wildfires in the last several years. These natural disasters occur with some regularity on their own, but many believe the latest ones are connected to the effects of climate change. The county has been experiencing higher temperatures and droughts as well. As a result of these challenges, Sonoma County’s government set a goal for the county to be carbon neutral by 2030. The airport solar power installations fit within the carbon-free plan. (The California state government has a goal for California to be operating on clean, carbon-free electricity by 2045.)

Jon Stout, the Sonoma Airport Manager, and Rachel McLaughlin, ForeFront Power’s Vice President of Sales & Marketing, provided some insights to CleanTechnica about the new solar power systems. (The last three answers are from ForeFront.)

Indiana farmers embracing organic methods as demand for products grows

Posted by in categories: food, sustainability

ANDERSON — For Sam Johnson, organic farming isn’t only a practical way of protecting the environment. It’s also a vital part of a healthy lifestyle.

“My main reason for doing it is just to get away from all these problems we’re having with herbicide and pesticide resistance,” Johnson said. “We’re just getting back to the natural ways our bodies process food.”

Organic farming is becoming undeniably more mainstream in the U.S. agriculture industry. According to an analysis of data in the USDA’s 2019 Survey of Organic Agriculture by Commodity.com, the number of organic farms in the U.S. rose by more than 50% in the last decade. The country’s estimated 16,500 organic farms now cover about 5.5 million acres, a 38% increase from 2008.
