This striking chart shows why solar power will take over the world

Over the past few years, many graphs have been worth thousands of words on the rise of solar power. It’s almost impossible to overstate how important the revolution that is happening right now is, and like most transitions, most people will only realize what’s going on after it’s mostly over. But not you guys and gals, you are ahead of the curve, and you’re grasping the importance of all this. In fact, I’m sure that many of you are driving this progress forward and helping it happen!

The chart above clearly shows that all of the solar power that we’ve installed on the planet until about 10 years ago basically didn’t amount to anything compared to what has been built in recent years. At some magical threshold, the price of solar per watt (in orange) hit some tipping point and installation exploded (the blue part), dwarfing anything from the past. And the beauty of having exponential growth on your side is that very quickly, even the current blue spike will look tiny. In 2020 or 2030 we’ll look back on 2015 and it’ll barely register as the beginning of the curve on the chart.

Here are a few other very telling charts that clearly show why solar will take over the world:

This one is particularly striking because it goes back all the way to 1949 and shows other sources of energy. Solar was so expensive for most of that time that it didn’t even show on the chart, and price comes crashing down rapidly only at the very end.

To close, here’s your fact of the day: Solar capacity worldwide is 53x higher than it was 9 years ago. How’s that for growth?

Πώς θα βρεις αληθινά φρούτα και λαχανικά χωρίς επικίνδυνα φυτοφάρμακα

Πριν λίγο καιρό, με έρευνά μας αποκαλύψαμε την ύπαρξη επικίνδυνων φυτοφαρμάκων για το περιβάλλον και την υγεία μας σε φρούτα και λαχανικά τα οποία πωλούνται στην ελληνική αγορά. Ουσιαστικά, αποδείχθηκε αυτό που ξέραμε ήδη: στην Ελλάδα γίνεται ανεξέλεγκτη χρήση φυτοφαρμάκων (νόμιμων αλλά και παράνομων).

Ο βιομηχανικός τρόπος με τον οποίο παράγεται η τροφή μας έχει δώσει προτεραιότητα στην ποσότητα και την ταχύτητα αλλά όχι στην ποιότητα. Η τροφή μας καλλιεργείται με αφύσικο τρόπο. Ειδικά στη χώρα μας όμως, η κατάσταση είναι δραματική αφού η πολιτεία δείχνει να μην ασχολείται καθόλου. Το πρόβλημα αποδεικνύεται και από τα αποτελέσματα των αναλύσεων της Greenpeace αλλά και από το γεγονός πως αρκετές φορές, ελληνικά προϊόντα για εξαγωγή έχουν θεωρηθεί ακατάλληλα και δεν έχουν γίνει δεκτά από άλλες χώρες.

Around $80 billion wasted on power for online devices in 2013

More Data, Less Energy coverSimple measures can keep problem of inefficient ‘network standby’ from worsening in years ahead, IEA report says

2 July 2014   Paris

Today, the world’s 14 billion online electronic devices – such as set-top boxes, modems, printers and game consoles – waste around USD 80 billion each year because of inefficient technology. By 2020, the problem will considerably worsen, with an estimated USD 120 billion wasted. But a report by the International Energy Agency points to a different path, identifying simple measures that can be implemented now to improve energy efficiency in networked devices, resulting in massive savings of energy and money.

48 hours that changed the future of the rainforests

Glenn Hurowitz sat down for his Thanksgiving meal discouraged. He’d spent 2013 flying halfway around the world to cultivate a fragile relationship with Kuok Khoon Hong, CEO of the world’s largest palm oil corporation, Wilmar. Kuok was the linchpin, Hurowitz believed — a single person who might turn the entire palm oil industry around. Wilmar buys palm oil from 80 percent of the world’s suppliers. If Kuok committed to buying only from farmers who promised not to cut down the rainforest, it would set off a chain reaction that might save hundreds of species from extinction and squelch one of the world’s biggest sources of carbon emissions. But after months of progress, the signals he’d been getting from Kuok were not encouraging.

Hurowitz emailed his co-workers at Forest Heroes, the nonprofit he’d founded, telling them to prepare for a protracted struggle. “I said, ‘Suit up, we’re going to war’,” Hurowitz told me. Then he got into bed, deflated. As he was settling in, his iPhone chimed a new text message. It was Scott Poynton, head of The Forest Trust, who had been working closely with Hurowitz and Kuok. Kuok was ready to make a commitment, the text said.

15 before-and-after images that show how we’re transforming the planet

Human beings have replaced nature as the dominant force shaping Earth. We’ve cleared away forests, dammed up mighty rivers, paved vast roads, and transported thousands of species around the world. “To a large extent,” two scientists recently wrote, “the future of the only place where life is known to exist is being determined by the actions of humans.”

So what does this look like? In recent decades, NASA has been tracking the major transformations we’ve wrought via satellite. In its “Images of Change” series, the agency has posted a number of before-and-after images showing the exact same rainforest or glacier or city years or decades apart. The differences are often breathtaking. Here are 14 of the most revealing changes:

Humans have been clearing forests to make way for farms and pastures for at least 7,000 years. And as the world’s population soars past 7 billion, the pressure for cropland is only growing. Continue reading 15 before-and-after images that show how we’re transforming the planet
