The 5 countries that lead the way toward 100% Renewable Energy

Last year (2014) was an exciting year for renewable energy. For example, in December last year, wind turbines alone provided around 1,279 MWh of electricity to the Scottish national grid, enough to supply the electrical needs of 3.96 million homes (164% of households).

According to Bloomberg New Energy Finance’s latest energy investment report, China led as the world’s largest investor in renewables, with the U.S. coming in second place.

Worldwide, around 100 gigawatts (GW) of solar and wind power capacity were built in 2014—up from 74 GW in 2013—and nearly during every month the headlines were filled with record generation in cities and countries across the world.


Here is the list of FIVE records that were broken in 2014:-

1. Denmark sets world record for wind

Denmark set a new world record for wind production in 2014, getting 39.1% of its overall electricity from the clean energy source.

The latest figures put the country well on track to meet its 2020 goal of getting 50% of its power from renewables.

Denmark has long been a pioneer in wind power, having installed its first turbines in the mid-1970s, and has even more ambitious aims in sight, including a 100% renewable country by 2050. Last year, onshore wind was also declared the cheapest form of energy in the country.


2. UK wind power smashes annual records

In the UK, wind power also smashed records in 2014, as generation rose 15% from 24.5 TWh hours to 28.1 TWh. The country now generates enough wind energy to supply the needs of more than 6.7 million UK households.

A combination of grid-connected wind farms and standalone turbines produced 9.3% of the UK’s electricity demand in 2014, up from 7.8% in 2013 and the latest data follows a string of wind power records announced in the second half of last year.


3. Renewables provide biggest contribution to Germany’s electricity

Renewable energy was the biggest contributor to Germany’s electricity supply in 2014, with nearly 26% of the country’s power generation coming from clean sources.

Electricity output from renewables has grown eightfold in Germany since 1990, and the latest data further highlights the dramatic shift towards clean energy taking place in Europe’s largest economy.


4. Scotland sees “massive year” for renewables

In December last year, wind turbines alone provided around 1,279 MWh of electricity to the national gird, enough to supply the electrical needs of 164% of Scottish households, or 3.96 million homes.

The latest figures further highlight the record year seen for renewables in Scotland, with wind turbines providing an average 746,510 MWh each month—enough to supply 98% of Scottish households electricity needs. Over 6 months of the year, wind generated enough power to supply more than 100% of Scottish households.


5. Ireland hits new record for wind energy

According to figures record by EirGrid on Jan. 7, 2015, wind energy had created 1,942 MW of energy, enough to power more than 1.26 million homes.

And while we are still only a week into 2015, this announcement marked the second time this year the country has seen this record broken. Windy conditions in Ireland meant the country saw not one but two wind energy records set already this year.


The Green Mechanics: Renewable resources as the main sources of energy isn't too far away from matching the finite sources.

Should be good for us.

New world record for PV module output: 324.5W by Trina Solar

Typical multi-crystalline PV module (not Trina's) is shown on the left-most.

Trina Solar - the second largest manufacturer of solar panels (behind Yingli Solar) - has set a new world record for power output from a high efficiency multi-crystalline silicon PV module.

Called Honey Plus, the multi-crystalline silicon PV module reached a new power output record of 324.5Wp. This has been independently certified by TUV Rheinland. 

Currently in pilot production, the multi-crystalline silicon module is composed of 60 high-efficiency Honey Plus multi-crystalline silicon cells (156×156mm2), including back surface passivation and local back surface field.

Recently, the Company set a new record for its Honey Plus p-type PERC cell which reached an efficiency of 20.76% - independently confirmed by Fraunhofer ISE CalLab in Germany. 


Trina Solar has set 4 new world records in 2014 for p-type PERC cells and modules, namely:
  • new efficiency record for large-area (156×156 mm2) p-type silicon substrates (21.40%) for mono-crystalline cells
  • new efficiency record for large-area (156×156 mm2) p-type silicon substrates (20.76%) for multi-crystalline cells
  • new peak power output records for commercial PV modules (335.2Wp) for mono-crystalline cells
  • new peak power output records for commercial PV modules (324.5Wp) for multi-crystalline cells.


The Green Mechanics: This could only mean one thing - More power squeezed from those panels on your rooftops.
