Revealing the Dark Side of Wind Power

Various research are being conducted on the use of renewable energy.Even though renewable technologies helps the environment,these can come up with environmental cost.

One of the studies have found out that the power available from the wind energy is limited.Over use of this wind energy can lead to the rise in temperature over the earth's surface. This rise in temperature is mainly due to the alteration of the atmospheric flow by the turbines.

It was found that the energy generated from large wind plants are less when compared to small ones. This is because in larger wind farms one turbine can disrupt wind flows and reduce the energy-gathering efficiency of other turbines nearby.

The interaction of the turbines in the vast farms leads to  the rise in temperature in those regions itself, which is due to the redistribution of heat in the lower atmosphere.

These studies shows the limitation of wind energy over the solar energy, although wind energy is contributing significantly to  energy supplies in various nations.

Running on fuel-cell technology

This article talks about the use and the application of fuel-cell technology. A fuel cell is a device that uses a source of fuel, such as hydrogen, and an oxidant to create electricity from an electro chemical process. A fuel cell converts chemical energy to electrical energy.

Germany has adopted this technology. The launch of hydrogen-powered train services in Germany is all about the article. Two Coradia iLint trains are now running passenger services in Lower Saxony with the use of fuel-cell technology. Sources say that, there are plans to induct atleast 14 more such "Hydrail" trains in Germany.The use of  fuel-cell technology is much more efficient and the usage of renewable energy is made possible as renewables are cleaner than thermal power sources and they also tend to produce excess energy at specific times.

Tata Power, HPCL tie up to set up EV charging stations.

Dated : 28 SEPTEMBER 2018
Published on : Business Standard.

Tata Power and HPCL has signed an MoU for setting up commercial charging stations for Electric Vehicles. The news say that the charging station will be set up at the HPCL retail outlets and other locations across India. They both have also agreed to colloborate further for Planning, Development and Operation of  charging infrastructure for electric vehicles such as e-cars, e-rickshaws, e-bikes, e-buses etc. THe sources also say that Tata Power and HPCL will also explore areas of opportunities and collaboration in related fields like renewable energy avenues.

Alarm! A change for the best is neccessary for the planet.

The UN has called the crisis urgent and decried the lack of global leadership to address the issue of Global Warming. Secretary General, Antonio Gutteres, warned that the world is facing a " direct existential threat" and must rapidly reduce or stop usage of fossil fuel by 2020 to prevent "runaway climate change".

Renewable energy is the alternative for fossil fuels. It must be promoted to reduce the Social Cost of Carbon incurred by the nation of the world. Use of renewable energy will significantly and dramatically minimise and mitigate the backlash of damage done to the environment which led to the global temperature increase.

Alarm bells!

Govt's first solar panel manufacturing tender draws Zero response( 28 Sep 2018 - Business standard)

The government's first tender for 3Gw of solar panel manufacturing ,along with 10Gw of power plant has received no bids. The tender was first issued in May this year and extended several times owing to resistance from the industry over specifications. 

Major players not accepting this bid, because that there is no funding push from the centre ,which reduces the viability of solar manufacturing in India Government across the world including china support solar through subsidy. In India, there is market uncertainty due to high import coupled with interest and capital cost.The tender for setting up solar cell and module manufacturing plant - for an aggregate capacity of 5Gw linked with solar PV projects in India on "build own operate" basis issued in May 2018.

India leadership in solar energy

 India and France had together announced the International Solar Alliance parallel to the Paris climate change summit in 2015.
 Its goal is to make big investments in solar energy in developing countries so that they can both fight rapid climate change and meet a rising energy demand.
 ISA plans to mobilize a trillion dollars to help create at least 1,000 GW of solar power capacity by 2030.
India’s target it to raise a solar power capacity of 100 GW by 2022, which requires quadrupling existing capacity in four years. But there are some very real policy challenges.
 For example, import duties on solar cells, that are intended to encourage domestic manufacturing, come with the side effect of slower capacity addition.

Running on fuel cell technology

The launch of hytrogen powered train service in germany
mark a break through in the commercial use of fuel cell technology.
it is the cleanest of technology since the waste product is plane water.
also fuel in a fuel cell is inexhaustible and highly efficient.
the coradia ilint trains have a range of abut 1000 km on a single hytrofen tank.

Solar powered CIAL airport wins UN Environmental Award

Solar Powered Cochin International Airport Wins UN Environmental Award

Cochin International Airport Limited, (CIAL) has won the UN environmental award for Entrepreneurial Vision. CIAL got the award for using sustainable energy.

It started with 100 Kilowatt pilot project in 2012, later found that it could produce 400 kilowatts of power. So they thought of scaling it up. Today the capacity of CIAL is 29.5 megawatt of solar energy, which is providing 120,000 units of power everday. CIAL is 100% on renewable energy for all its operations. Also the surplus energy generated can be used for cloudy days or monsoon seasons, when the sun rays are less frequent. Currently have eight locations for the panel.

The land where solar panel are kept is used as a farm for growing organic vegetables, which roughly produce 60 tons of vegetables.

In future CIAL target was to produce at least 100 gigawatts of power for the national grid from renewable source by 2022.
