Energy conversion efficiency

matter derived from living, or recently living organisms. Biomass can be used as a source of energy and most of the time it refers to plants or plant-based materials that are not used for food, and are specifically called lignocellulosic biomass. As an energy source, biomass can be used directly by combustion to produce heat, or indirectly after converting it to different forms of biofuel. The conversion of biomass to biofuel can happen by different methods which are put into three categories: thermal

The worldwide demand of energy has been increasing considerably. Up to 2030, it is supposed to be 60% higher than today (B. SCHMITZ, 2013). Currently, non-renewable energy sources, like coal and oil, are more commonly used, since they are cheaper than renewable energies. In the European Union, 80% of the energy consumption demands are covered by fossil sources (B. SCHMITZ, 2013). But, non-renewable energy sources are running out and they are also very harmful for the environment, since they generate

and electric vehicles. Carpooling, public transit, and hybrid cars reduce the amount of fuel per person used to get to a destination. On the other hand, electric cars use energy stored in batteries and therefore have no need to burn fossil fuels as a power source. The electric motor is also much more efficient at energy conversion than the internal combustion engine. Tesla Motors, an American electric car design and manufacturing company, made headlines when they released the first fully electric sports

trying to fight back the increase in the greenhouse gas emission (GHG) is through the use of combined cycle power plants used to created energy for the population. A gas turbine generator produces electricity and waste heat is used to make steam to generate additional electricity through a steam turbine. The gas turbine is one of the most efficient one of the conversion of gas fuels to mechanical power or electricity, Through the research of the science of climate change, it is important to look at

A FRAMEWORK FOR EPBT CALCULATION OF ROOF MOUNTED PHOTOVOLTAIC SYSTEMS Introduction Currently, most of the world’s energy is derived from fossil fuels (World Energy Resources 2013 Survey). Fossil fuels are a limited resource and might not be able to meet the future energy requirements of the world for too long (Shafiee and Topal 2009). Apart from being non-renewable, these are also significant contributors of greenhouse gases to the environment leading to air, water and land pollution (Marland and

of electrical energy is very severe, that no one could live without it. In such a condition, in India and especially in southern India there is a great demand for electricity. This article refers to such a problem and also gives a solution .Moreover calculations based on the solar potential in India and the possibilities of constructing Solar Power Plants in India is also discussed here. Some methods for storing the huge potential of solar

order to meet the energy demand and a sustainable future, renewable energy is a better way to achieve it. Commonly, renewable energy is defined as energy which is able to be captured from existing natural resources that are replenished rapidly, such as flowing water, sunshine, wind, geothermal heat flows and ocean [2]. Renewable energy technologies are required to provide technologies to use one or several renewable energy resources. There are some different types of renewable energy technologies, which

Embedded Systems by McGraw-Hill Education. The topic of the case study is “Solar Tracking for Optimum Power Generation”. The demand for energy is increasing day-by-day and has led to uneven global distribution of primary energy consumption. The non-renewable energy resources like coal and petroleum will eventually run out. So the only option left will be renewable energy resources like sun, wind, waves and

possess the potential for the low cost and large area production on mechanically flexible substrates. These are lightweight and suitable for the applications such as foldable and portable solar cells. Organic photovoltaics (OPVs) have not achieved efficiencies comparable to the inorganic solar cells due to poor charge carrier mobility [1]. Recent developments of optimizing the organic absorbing materials have shown encouraging device performance towards overcoming the challenges associated with commercialization
