The approach of circular economy is: make – use – maintain/ reuse/ remanufacture/ recycle. Waste should be seen as source of valuable resources. Products should be repaired, remanufactured and reused.
A genius idea in times when resources get scarce – be it oil, water or different metals and when the world has to face a growing population. It is estimated that 9.2 billion people will live on earth in 2050 (UN).

The world in 2050: That world is a fair, high-tech and sustainable one – with advances that mean food for all, a reformed capitalism, and a circular economy.

But the road getting there will not be easy.

The more I look at the two sides – the environment and the economy – the more convinced I become that the way forward is to fully integrate resource efficiency into the way we live and do business in the world.

We know why a circular economy is a good idea. At the moment the world is still locked into a linear production chain that is resource intensive. We obtain resources and then discard them as waste.

In a circular economy, almost nothing is wasted. Read More

the Power-to-Gas (P2G) approach can facilitate a transition from natural gas to a ‘green’ mixed gas by making use of both of the existing energy grids on a global scale

Power-to-Gas is the process of converting surplus renewable energy into hydrogen gas by rapid response electrolysis and its subsequent injection into the gas distribution network. One of the most promising energy storage systems to storage renewables into the existing EU gas infrastructure.

The hydrogen produced is injected into the natural gas system to displace natural gas, so reducing greenhouse gas emissions and reliance upon fuel imports.

If the power is derived mainly from renewable power sources, only low-carbon hydrogen will be produced. Thereby the Power-to-Gas (P2G) approach can facilitate a transition from natural gas to a ‘green’ mixed gas by making use of both of the existing energy grids on a global scale.

The future of the world is urban

From 1950 to 1980 the number of people living in favelas in Rio de Janeiro alone increased from about 170,000 to more than 600,000, and by the early 21st century it was estimated that there were as many as 1,000 favelas there.

Given the rate of change, our world will be a very different place by 2040. More and more people are moving to cities.

How will billions of city-dwellers access what they need without putting intolerable strains on the planet?

How can we plan now for more sustainable ways of life in a radically different world?

These programs serve SCE’s residential, commercial and industrial customers who, in exchange for bill reductions, have agreed to reduce their energy consumption when called upon to do so and in that way ease the stress on the electric system, especially in times of peak power demand.

Southern California Edison (SCE) announced the integration of an estimated 1,118 megawatts of demand response resources into California’s wholesale energy markets.

And 320,000 customers have agreed to join. Read More

The shift to renewables is happening shockingly fast, but not fast enough to prevent perilous levels of global warming.

A new report from Bloomberg, looking ahead to the next 25 years of renewables, has been containing something new. But for who want to know the highlights. Here they come. 

  • The costs of a power plant based on solar panels, will be halve, the next 25 years

Increased solar power threatens energy companies

Energy companies need flexible plants that can quickly respond to peaks in demand and supply

Because of the growth in the number of solar panels in Europe, Energy Companies have to consider new business models.

Strategy consultant Berger:
‘By 2030, solar power will supply half of the peak demands for energy.’

The fact that more and more consumers produce their own power, is forcing energy companies to think about their future. On sunny days Europe scores enormous energy surpluses. This distorts the market for energy companies. They feel the impact of solar energy and therefore must adjust their operations. Read More
