Overview of the Solar Energy sector in India

India has a vast supply of green energy resources, and has a significant program for deploying these resources. An exclusive ministry for renewable energy called Ministry of Non-conventional Energy Sources later renamed as Ministry of New and Renewable Energy (MNES) has also been set up.

According to the recent report on Renewable Energy in …

Benefits of Solar Why Go Solar?

1. Solar PV or solar hot water systems reduce, or can completely eliminate, the amount of electricity you have to purchase from your utility or electric service provider to power your home. Using solar power helps reduce our energy reliance on fossil fuels.
2. The electricity generated by your solar power system is clean, renewable and reliable. It will help reduce the amount of greenhouse gases – a major contributor to global climate change.
3. Solar PV or solar hot water systems save you money on your electricity or natural …
   

Wind energy sector still remains one of the fastest growing renewable energy sectors in the world even despite the recent slowdown of wind power industry in United States. Despite the fact that wind power isn’t a perfect source of energy it certainly has more benefits that drawbacks which should be more than enough for wind power to become (together with solar power) the most important source of clean energy in years to come.

The two most talked about drawbacks of …

A large portfolio of microgeneration technologies is now available: solar PV, heat pumps and small wind turbines are affordable and suited to domestic and business customers and communities’ needs.
There is nothing new with generating power from the wind. Small wind turbines made this old concept accessible for all households, companies and communities willing to cut their carbon footprint and invest for the future.

Protect the environment
A small wind turbine is one of the most …

Passive solar is as simple as using the sun’s energy to light a room. The biggest benefits with passive solar are achieved by implementing passive solar techniques in the building stage, although an existing structure can be modified to include passive solar elements. Using passive solar is good for the environment, saves energy, reduces utility costs, requires little maintenance and saves natural resources.

Saves Natural Resources

Passive solar energy uses the sun’s energy for heat, light and power. It does this by direct conversion of sunlight into energy without consuming any dwindling natural resources. Using passive solar reduces the need for fossil …

… both viable sustainable alternative energy and commercial electricity generation. It is both free of pollutants and truly self-sufficient energy. The turbines can be manufactured in almost any industrialized country, and the wind is obviously anywhere. Although not the least expensive form of electricity generator in standard terms, wind energy for home still provides many benefits.

Wind power works by transforming the kinetic energy present in wind into mechanical energy and then into electrical energy. The process of converting kinetic energy into mechanical energy utilizes a technique as old as the typical windmills. Wind rotates the turbine blades, which are specifically …

I take issue first with the idea that fuel input to coal-fired boilers is not cycled down when the electrical output of the generators they drive is cycled down. It is true that many coal-fired boilers are less efficient at lower output levels, but for many coal units there is a direct simple relationship between fuel input and unit output over a rather large operating range. And while even the lowest-efficiency coal-unit capacity factors have been increasing in recent years, many of them do still cycle on a daily basis. But there is no need to theorize — the EPA posts hourly records of both heat input and MW output for almost every coal unit in the country. …

… Eight More Cape Winds? questioned the efficacy of Massachusetts partnering with research institutions and offshore wind energy experts to reduce the cost of offshore wind by 40 percent by 2020 and 60 percent by 2030.

Norton’s article, like so many others that have monopolized media headlines for years, discounts the relevance of green energy research and innovation. Are American journalists simply dismissing the economic adrenaline that a Clean Energy Industrial Revolution would deliver, or do they genuinely lack the awareness of resource economics, which compelling pairs job creation, corporate profits, and …

Solar Energy Benefits

So, you want to install solar panels on your home. But, before you do so, you need to know about solar energy benefits. Fortunately, there are many!

Of the solar energy benefits, the first and foremost item to note is that solar power does not produce any waste or pollution, unlike most of the other …

Proponents of renewable energy are always challenged on its practicality. The fact is we’re past that as it has become rather an issue of necessity. As our environment bleeds away at an alarming rate from the effects of runaway waste levels from conventional energy, alternative sources of power must be deployed urgently. The obvious solution is renewable energy such as wind, water and sunlight.

The need and advantages of renewable energy are irrefutable. With oil and gas prices going the way they are, it’s a no-brainer from a financial standpoint. Also, there’s mileage in civics and morals …
