 Scotland will begin building the world's largest floating wind farm. The construction of the wind farm will start this year after its developers were granted a seabed lease on Monday. The wind turbines will operate around 12 to 18 miles off the coast of Peterhead, Aberdeenshire. The Norwegian energy company, Statoil who is building this project plans to build five 6 MW turbines. The Hywind project expects to have a total capacity of 30 Megawatts.

 Unlike other wind turbines which use the seabed as a foundation, this project will apply floating steel tube tethered to the sea floor as the foundation for the turbines.


 “We are very pleased to develop this project in Scotland, in a region with a huge wind resource and an experienced supply chain from oil and gas,” said Leif Delp, project director for the Hywind Scotland project. “Through the hard work of industry and supportive government policies, the UK and Scotland is taking a position at the forefront of developing offshore wind as a competitive new energy source.”

The project expects to power 20,000 homes once completed. The process of erecting wind turbines will begin at 2017 and electricity production will commence at the end of next year.

Scotland is making use of renewable energy to the full extent. Last year, 50% of Scotland's electricity came from renewables and just this year, they shut down their last coal plant.

According to a study conducted by the National Energy Network (REN) and the Portuguese  Renewable Energy Association (APREN), Portugal ran entirely on renewable energy for 4 consecutive days. The data collected from the study said that the country ran 107 hours without using any source of non-renewable energy.


Portugal record of using renewable energy is not new. In 2013, renewable energy provided 70% of the country's electricity needs in the first quarter. Portugal has a favorable weather condition that increases the wind and water flow which helps in harnessing renewable energy quite easily. Moreover,  less consumption of energy and use of renewables by the Portuguese citizens has been responsible for such growth in the energy sector.

Renewable energy has become the latest trend now, given its low cost and flexibility. San Diego which produces the second largest electrical output from solar energy in the US has laid out a new plan to cope with climate change.

The new plan initiates to run the city completely on renewable energy by 2035. The city also plans to reduce 50% of the greenhouse gas emission by 2035. Another target of the plan is to create Jobs through manufacturing and installation of solar panels.

“San Diego is a leader in innovation and sustainability,” the Climate Action Plan reads. “By striking a sensible balance between protecting our environment and growing our economy, San Diego can support clean technology, renewable energy, and economic growth.”

San Diego is not the only city, trying to go 100% renewable. San Francisco, Sydney, and Vancouver have already joined the growing list of cities committed to run completely on renewable energy.

With recent record of Costa Rica running 99% on electricity generated from renewable energy, this plan from San Diego doesn't seem too far-stretched.

Usually, solar energy is generated by the light coming from the sun. However, a team of Chinese scientist has tried an unconventional way to harvest solar energy from raindrops.

The team of scientist from the Ocean University of China in Qingdao used a Graphene-coated solar panel to carry out the test. Graphene which consists of a single layer of carbon atoms can produce electricity when exposed to salt water. Using this effect, the scientist were able to successfully carry out the test.

The test panel was able to generate hundreds of microvolts which is quite low in comparison to standard AA battery.


The short comings of this technology are that it converts only 6.5 percent of the energy it gets while conventional solar panels which use sunlight have an efficiency rate of 20%-30%.

"All-weather solar cells are promising in solving the energy crisis," the team says.

"A flexible solar cell is presented that is triggered by combining an electron-enriched graphene electrode with a dye-sensitised solar cell.

 "The new solar cell can be excited by incident light on sunny days and raindrops on rainy days."

According to the National Renewable Energy Laboratory, rooftop solar photovoltaics can provide nearly 40 percent of electricity in the U.S. The analysis from NREL predicts rooftop solar power a technical potential of 1,118 gigawatts of capacity and 1,432 terawatt-hours of annual energy generation, equivalent to 39 percent of the nation's electricity sales.

 The study was conducted by NREL using LiDAR (light detection and ranging) data and PV-generation modeling across 128 cities nationwide. The new analysis has doubled NREL's last estimate, which was 664 GW of capacity and 800 TWh of annual energy generation.

"This report is the culmination of a three-year research effort and represents a significant advancement in our understanding of the potential for rooftop PV to contribute to meeting U.S. electricity demand," said Robert Margolis, NREL senior energy analyst and co-author of the report

100% emissions-free electric Double Decker bus will soon run on the streets of London. The electric bus developed by Chinese car manufacturing company 'BYD' is 10.2m long with 81 passenger seats. The bus has also standing spaces. It is specially designed to run on urban streets and can travel 190 miles with a single charge. According to pv magazine, the bus takes 4 hours to fully recharge and its batteries can generate 345 kWh of power. 

“The Mayor of London challenged us saying that he did not believe an electric Double Decker was technically feasible but we took up the challenge and in less than two years created the bus Londoners can see today,” said Isbrand Ho, Managing Director of BYD Europe. “This is not a hybrid bus but a totally emissions-free product that will give London a world leading position in its efforts to improve air quality.”

BYD is one of the most reputed Auto companies in Asia and is also the largest selling Chinese car brand. The company sold 506,189 passenger cars in China in 2013.

BYD electric buses called K9s already run on the streets of major cities in China and as of 2015, the company has sold about 6,000 of electric buses worldwide.

Panasonic has set a new solar photovoltaic (PV) module conversion efficiency record of 23.8% at a research level. National Institute of Advanced Industrial Science and Technology (AIST) has verified this latest research.Sun Power's previous world record of 22.8% conversion efficiency of PV module was broken by Panasonic with a full percentage point. Panasonic also holds another record for highest conversion efficiency of its crystalline-based solar cells at 25.6%.

Panasonic's press release states: "Panasonic developed a unique silicon heterojunction structure composed of crystalline silicon substrate and amorphous silicon layers, and has continuously improved its photovoltaic module HIT using silicon heterojunction since the start of commercial production. This new record was achieved by further development of Panasonic‘s proprietary heterojunction technology for high-efficiency solar cells and modules adopting a back-contact solar cell structure.”
