Let’s Power The Future-Here Comes The Sun.!

  • Buffer

After the Fukushima nuclear disaster, the German government decided to abandon nuclear power, closing eight plants immediately and shutting down the remaining nine by 2022. Their solar power plants were able to produce a world record 22 Giga watts of electricity per hour - equal to 20 nuclear power stations at full capacity..!!

If they can do it, why can't we? Wind energy alone could provide enough power ten times over to provide for all of our needs!

Nuclear plants will be replaced by renewable energy sources such as wind, solar and bio-mass. 22 Giga watts of solar power per hour fed into the German power grids, met nearly 50 percent of the nation's midday electricity needs.

It should be seen as a great auger for bright, clean and safe energy environment for the entire world and hope for every developing and underdeveloped countries to cut their huge cost, they are bearing for energy requirements.
Here Comes The Sun !

Never before anywhere has a country produced as much photovoltaic electricity. Germany came close to the 20 GW mark a few times in recent weeks. But this was the first time they made it over. The record-breaking amount of solar power shows one of the world's leading industrial nations was able to meet a third of its electricity needs on a work day, Friday, and nearly half on Saturday when factories and offices were closed.
Government-mandated support for renewable has helped Germany became a world leader in renewable energy and the country gets about 20 percent of its overall annual electricity from those sources.

Germany has nearly as much installed solar power generation capacity as the rest of the world combined and gets about four percent of its overall annual electricity needs from the sun alone. It aims to cut its greenhouse gas emissions by 40 percent from 1990 levels by 2020.

Solar Power Evolution
Some critics say renewable energy is not reliable enough nor is there enough capacity to power major industrial nations. But Germany is eager to demonstrate that is indeed possible.

The jump above the 20 GW level was due to increased capacity this year and bright sunshine nationwide. The 22 GW per hour figure is up from about 14 GW per hour a year ago. Germany added 7.5 GW of installed power generation capacity in 2012 and 1.8 GW more in the first quarter for a total of 26 GW capacities.

This shows Germany is capable of meeting a large share of its electricity needs with solar power, it also shows Germany can do with fewer coal-burning power plants, gas-burning plants and nuclear plants.

This should be an eye opener of the nations involved in dangerous nuclear deals or in nuclear plantation. What for and where they are heading for to keep their promise of giving light to people or disastrous, dangerous and unlivable environment to their gen –next. 

 Hopes lies everywhere and trends, for what have been achieved so far, are also in favor, now one need a strong will power to get the things on track for better tomorrow.

Could The World Reach A 100 Percent Renewable Energy Goal

  • Buffer

Could the world reach a 100 % renewable energy target in less than 20 years? New research reveals some facts regarding this milestone that gives a firm hope and strengthen our initiatives,thinking in this field.  
A report published in the journal Energy Policy claims that by 2030, we can achieve 100 % renewable energy if the proper measures are taken.
What exactly are these measures? According to PhysOrg, over 80 percent of our world's energy supply currently comes from fossil fuels. We would need to build approximately four million wind turbines, nearly 2 billion solar photovoltaic systems, and about 90,000 solar power plants. The 5 MW wind turbines needed are up to three times the capacity of most of our current wind turbines. Possible? Perhaps.

solar wind renewable energy

Germany and China have both already built 5 MW offshore turbines. A few dozen utility-scale solar plants already exist. Plus, the researchers believe that all of the major necessary resources are available - the only "material bottleneck" lies in obtaining rare earth materials, supplies which could be increased with more mining or recycling.
Human beings are probably the biggest blockade in achieving a renewable energy goal.
What do you think? Can the world achieve 100 percent renewable energy by 2030?
Look at the some facts regarding solar and wind power energy..
1.The unit cost of wind and solar are coming down.the time to transition is NOW before PEAK OIL raises the cost of oil and damages the world economy. Rising demand for oil from China and India will soon exceed the world supply raising the price of oil for all.We saw what $147/barre­l oil did to the economy in 2008, and exceeding day by day.

2. Is this a joke right? The authors of the study list the following needed investment­s for this to happen:
3,800,000  5 MW wind turbines,
49,000  300 MW concentrat­ed solar plants
40,000  300 MW solar PV power plants,
1.7 billion  3 kW rooftop PV systems,
5350 100 MW geothermal power plants,
270 new  1300 MW hydroelect­ric power plants,
720,000  0.75 MW wave devices, and
490,000  1 MW tidal turbines
This cost of the first 3 items on the list is a cool $159 Trillion dollars compared to world GDP of $67 Trillion in 2007.
