In the eighteenth century, intellectuals, including French, have joined forces to get out of the western world & rsquo; obscurantism : c & rsquo; s & rsquo was; Enlightenment. Three centuries later, face the challenge of climate change, these lights sometimes seem to waver. In the energy sector, Progress is hampered by the persistence of entrenched beliefs about the cost and limitations of renewable energy and the maintenance of public policy to fossil fuels. Thus, key photovoltaic development scenarios (PV) provide a contribution around 5% the global supply & rsquo; electricity 2050. However, an objective analysis of this technology allows development prospects & rsquo; claim that photovoltaics could cover at least 20 to 25% global power needs 2050 and provide energy services to 1,3 billion people n & rsquo; will not have access aujourd & rsquo; hui. What for ?
In the early 2000, complete d & rsquo cost; a photovoltaic system was the & rsquo; about 750 $/MWh against less 70 $/MWh for other types of production & rsquo; electricity. Fifteen years later, PV's competitiveness is comparable to that of other technologies. C & rsquo; is because the photovoltaic solar is already competitive than 136 billion was invested worldwide in there 2014 ! D & rsquo; here 2050, technical developments will further reduce costs to achieve the & rsquo; about 35 to 50 $/MWh for photovoltaic ground facilities. Indeed, unlike other energy sources that are based on the classical physical, photovoltaics based on quantum physics, which offers potential d & rsquo; innovation much higher than those of conventional technologies & rsquo; electricity, and l & rsquo; energy in general. A l’inverse, production facilities d & rsquo; electricity from nuclear or fossil should see their costs increase due to increased security standards and the & rsquo; integration costs related to pollution.
No more than the cost, l & rsquo; photovoltaic solar intermittency of the not confined to a minor role in the global energy mix. D & rsquo; firstly, we should not underestimate the current capacity of the electricity network to absorb & rsquo; intermittently. Today, nearly half of the German electrical capacity is intermittent without the country is plunged into darkness. D & rsquo; other, the steering consumption is growing at both private individuals and professional and battery storage capacity itself is also becoming more competitive. The n & rsquo; is no coincidence that large banks, comme Goldman Sachs, UBS, German Bank, have recently published several reports providing an upheaval in the sector & rsquo; electricity related to the combination of solar photovoltaic developments, storage battery and steering consumption.
Thus, in a world ruled by clean energy, solar photovoltaic appears as a light d & rsquo; hope. With an increasingly favorable energy and environmental balance, it constitutes one of the cornerstones on which s & rsquo; support to develop new sustainable electrical systems.
C & rsquo; is also a great hope for those who n & rsquo; have access to the & rsquo; electricity as many rural populations & rsquo; & rsquo and Africa; Asia. Photovoltaic because & rsquo; it is flexible can bring energy services closer to the people : lighting, d & rsquo improving conditions of hygiene and food conservation, Access to & rsquo; information (via Internet), Recharging mobile phones, etc. And this, without requiring the prior sale of large and expensive power grids : coupling of photovoltaic solar with storage solutions or d & rsquo productions booster can quickly and significantly improve the living standards of hundreds of millions of people. Of course, this will be that & rsquo; a first step before & rsquo; interconnect these facilities with centralized renewable resources. But from the base, will d & rsquo; go faster in & rsquo; improvement of living conditions, providing the ability to deploy these forward peoples electric system adapted to their particularities with positive benefits for the & rsquo; local economy. C & rsquo; is the message that we are asking Heads & rsquo; states gathered for the EU Summit / Africa and the G20 to wear.
