travails of renewable power in germany - electricity storage

May 11, 2014 is an important day for renewable energy in Germany.
The largest clean energy market reached an enviable record, with the share of the renewable energy market reaching almost 75 in a few hours that day.
Germany faces its own dilemma on the road of choice.
Germany's love for renewable energy began decades ago.
Osha Gary Davidson noted that Germany's record of renewable energy dates back to the 1990 s and that renewable energy began speeding with the adoption of the Renewable Energy Act in 2000. (DISSENT, 2013)
"Electricity from renewable sources grew from 6 to 2000 to 2011. 8 to 20.
5 per cent of total electricity consumption-
"Power generation from energy sources such as wind and solar has almost tripled," Davidson clarified . ".
Almost everyone with a roof in Germany will install solar panels, produce electricity, and sell excess electricity to utilities at a fixed price guaranteed for decades.

Experience in Germany (2009)
Manuel frendel of the German Institute of Energy and others have severely criticized Germany's renewable energy policy, particularly through feed
In the tariff scheme.
What is the reality now? Mr.
Energy expert Will Boisvert believes that "despite the massive construction of new capacity, the generation of renewable energy, especially wind and solar energy, has grown slowly.
Germany did avoid power outages-
By opening new coal and gas power plants.
It turned out that renewable power was so unreliable and chaotic that it began to undermine the stability of the European grid and triggered international events.
The surge in renewable energy prices has triggered a strong rebound, including the government's proposal to cut subsidies and deploy rates "(DISSENT, 2013).

Renewable energy policies are bad for consumers, producers and the environment.
He felt that only the owners and solar panel installation companies benefited.
"The electricity bill for homes in Germany is about $0.
34/kWh is one of the highest rate countries in the world. About $0.
07/kWh is used directly to subsidize renewable energy, which is actually higher than wholesale electricity prices in Europe. . . . .
"Every year more than 300,000 households shut down their electricity because they can't afford their bills," he added . ". “Large-

The scale of power storage is not there yet, and nothing in the development pipeline is cheap enough within two orders of magnitude, Carlyle said, almost one out of every five German industrial companies plans or has moved capacity abroad because of the low cost of electricity.
After listing several issues, he claimed that other countries should not follow Germany's lead in promoting solar energy.
This seems to be an extreme view.
According to the New York Times, Germany's major industries have repeatedly expressed concern that the rapid and expensive expansion of renewable energy may weaken the strength of Germany's industrial base and ultimately endanger 800,000 jobs. (
New York Times, April 8, 2014).
Serious mismatch in Current Science (

Sukhatme has shown that India's annual electricity demand can be met through renewable energy alone.
However, he pointed out that due to the intermittent solar and wind energy,
There is a serious mismatch between the day and night changes in renewable energy generation and power demand.
He added that we must overcome many difficult technical challenges in order to fully meet the demand for electricitythe-clock basis.
India has an ambitious renewable energy plan, and we must learn from the experience of other countries, especially Germany,
The partnership between Germany and renewable energy is often seen as a model.
India must promote all power generation methods including solar and wind energy.
Plenty of sunshine and plenty of wind may lead to overproduction of the grid.
Balancing the grid could be a challenge.
The central government must organize a systematic review of the challenges facing India
