Our hunger for energy goes beyond all limits and will double in the next 20 years. But what available technologies could meet the growing thirst for electricity? And will we also have to cut power consumption? What can Europe learn from China? And could “decentralization” into so-called “microgrids” the future of energy?

What is supposed to be the largest and most efficient solar power plant in the world is currently being built near the Moroccan desert city of Ouarzazate. The Noor solar power plant, which means “Light” in Arabic, is due to be completed by 2020, when it will comprise 4 units. In its final expansion stage, Noor will supply a total of 1.3 million households with electricity. The sun is the most powerful source of energy in our galaxy and could theoretically supply all of humanity with electricity with ease, but what technologies do we have to usher in this new era of electricity?

Could wind power be a more promising alternative? Wind farms are being built at full speed around the world, but is wind energy really viable? Is the enormous investment in wind turbines at all worth it and can it meet our demand for electricity?

China has shown how quickly you can push ahead with the switch from fossil to renewable energy sources. China’s enormous economic growth in recent decades has made the Middle Kingdom the world’s largest energy guzzler. But China is also the world’s largest energy producer. A veritable energy revolution is currently underway. Almost 20 percent of the ever-growing demand for energy is now met by renewable technologies, and a large proportion of the solar cells used worldwide already come from China. What can Europe learn from China? One key to avoiding an electricity crisis could be “decentralization,” so-called “microgrids.” A quiet little town in the Swabian Allgäu region has shown it is possible to produce eight times as much electricity as it needs itself.

How Sea Cucumbers Can Help the Ocean

Sea cucumbers are a prized aphrodisiac in China. But like many coastal species they have been chronically overfished. One remote community in Madagascar has started a pioneering coastal-farming project with astonishing results.

The Ocean is facing environmental catastrophe. Overfishing is a ticking time bomb for both planet and people.

In one remote coastal village the locals appear to have found an unlikely solution. A strange little sea creature that’s a popular aphrodisiac and just possibly a fisherman’s salvation. In the first business of its kind in Madagascar, Dadiny has recently started farming these animals. Sea cucumbers.

Sea cucumbers are under threat. Growing them in designated and contained areas is helping to protect both this important species and other kinds of marine life here in the south-west of Madagascar. Because of the part sea cucumbers play in cleaning up the seabed it’s believed that they help maintain stocks of other marine life.

In this region, not just sea cucumbers, but all kinds of marine life have suffered from chronic overfishing. When marine conservationist Alasdair Harris first visited Madagascar in 2001 he was shocked to discover the extent of this devastation. To reduce this overfishing the NGO that Alasdair runs helped train 700 local fishermen and women in small-scale sustainable sea-cucumber farming. It’s meant many locals are no longer using the techniques that contributed to overfishing in this region. Alasdair’s research suggests fish stocks have doubled here since 2006. But it is not marine conservation that has fundamentally persuaded the local population to buy into aquaculture – It’s hard economics.

There’s a strong demand for sea cucumbers in Asia where they’re prized as an aphrodisiac. Farmers here can now make up to $50 a month, about twice that of a regular fisherman. While this is still substantially below the average global wage, it’s brought dramatic improvements in the local quality of life. NGOs, including Alasdair’s, are now working on similar farming ventures in other coastal villages around Madagascar. Localised efforts can only go so far in countering the vast damage to ecosystems across the ocean.

But in the face of an increasingly urgent crisis that could still be a very long way.
