The Oil Industry is Going Solar

Zachary Shahan writes at Climate Crock of the Week:

There’s no way around it — the future of energy is solar energy. But here’s the fun part: the future starts now.

Solar panels have been on the market for decades, but saying solar panels of today are the same as solar panels of the 1990s is like saying phones of today are like phones of the 1990s. True, you can’t play Tetris on your solar panels or listen to music via them, but who wants to climb onto a record-hot roof to do that anyway? Getting back to the central point here, it’s that the cost of solar has fallen off a cliff, and solar power is increasingly the cheapest option around. (see graph above).

Solar power prices are falling so fast that it’s hard for just about anyone to keep up. Last year, many of us jumped for joy as a record-low solar PPA was signed in Austin, Texas (for 5 cents/kWh).

New Report Shatters Myth of ‘Nuclear Renaissance’

If renewable energy advocates need more evidence that solar and wind are better investments than nuclear power, a new report may offer just that.

The findings come from the newly released World Nuclear Industry Status Report 2015, which looks at global nuclear developments over the past year.

Marking a first in five decades, Japan went without nuclear power for an entire year, the report states. And three of the world’s largest economies—China, Germany, Japan—as well as Brazil, India, Mexico, the Netherlands, and Spain, now all generate more electricity from non-hydro renewables than from nuclear.

In the UK, renewable energy, including hydropower, provided more electricity output than nuclear in 2014.

Global generation from solar was up 38 percent, and wind power increased over 10 percent.

Here’s How Wind and Solar Energy are Increasing CO2 Emissions

Almost everybody today agrees that it would be really smart (if not vitally essential) that we reduce the amount of fossil carbon we release from giant, tupperware-geological structures deep inside the earth.  But how would we accomplish freeing ourselves from coal, petroleum, and gas while maintaining a dependable flow of electricity?

Mainstream environmentalists currently advocate for generating energy from wind turbines and solar arrays, whose energy comes more-or-less directly from the sun.  With solar photovoltaic, solar thermal, and wind turbines we can produce electricity without generating any carbon dioxide (once these devices have been manufactured and placed on a field or ocean somewhere).   Unfortunately, one issue with these technologies is that the energy is intermittent.  With the wind dying down and the Sun being obscured by clouds or the night, these devices only actually generate electricity a small minority of the time, let’s say generously 30% of the time.… Read the rest

Utilities Wake Up – Rooftop Solar to Rival Conventional Power

Sun_in_the_skyPeter Sinclair writes at Climate Denial Crock of the Week:

I’m shouting this wherever I go. There is a revolution in energy production technology happening right now – it will be as disruptive to the utility industry as the internet has been to the communication industry. If states, utilities, and regulators don’t develop coherent strategies very soon to cope with unprecedented change, we are going to see a major economic train wreck within the decade over much of the country.

NYTimes:

For years, power companies have watched warily as solar panels have sprouted across the nation’s rooftops. Now, in almost panicked tones, they are fighting hard to slow the spread.

Alarmed by what they say has become an existential threat to their business, utility companies are moving to roll back government incentives aimed at promoting solar energy and other renewable sources of power. At stake, the companies say, is nothing less than the future of the American electricity industry.

Sun’s Magnetic Field About to Flip

Image unrelated. Everything’s fine.

The sun’s magnetic field is about to flip and cause solar powered zombies to rise from their tombs and feast upon the tender flesh of the living. It sounds alarming, but it actually happens with some regularity. They’re making me type this. Run. Run, damn you. Fear the dead. Pray for the living. Buy sunglasses.

Via E Science News:

Something big is about to happen on the sun. According to measurements from NASA-supported observatories, the sun’s vast magnetic field is about to flip. “It looks like we’re no more than three to four months away from a complete field reversal,” said solar physicist Todd Hoeksema of Stanford University. “This change will have ripple effects throughout the solar system.”

The sun’s magnetic field changes polarity approximately every 11 years. It happens at the peak of each solar cycle as the sun’s inner magnetic dynamo re-organizes itself.

Solar Plant Pollutes River in China … Riots Ensue

Solar PanelWhat does sustainability truly mean in an industrial world? Villagers in Zhejiang Province are wondering the same thing since the production of solar cells and batteries at a factory in the area has effectively poisoned their river and their children … Via the BBC:

Hundreds of villagers in eastern China have held three days of protests at a solar panel plant over pollution fears. Around 500 people started gathering at Zhejiang Jinko Solar company in Haining city, Zhejiang province, on Thursday. Some of protesters stormed the factory, overturning several company cars and destroying offices, officials said. Residents in the nearby village of Hongxiao said they became concerned after the deaths of a large number of river fish.

One 64-year-old villager told the Associated Press that the factory — located close to a school and kindergarten – discharges waste into the river and spews dense smoke out of a dozen chimneys.
