Carbon credits are a tradable permit schemes. They provide a way to reduce green house gas emissions by giving them a monetary value. A credit gives the owner the right to emit one ton of carbon credit. International treaties such as the Kyoto Protocol set quotas on the amount of greenhouse gases countries can produce. Countries, in turn, set quotas on the emissions of businesses. Businesses that are over their quotas must buy carbon credits for their excess emissions, while businesses that are below their quotas can sell their remaining credits. By allowing credits to be bought and sold, a business for which reducing its emissions would be expensive or prohibitive can pay another business to make the reduction for it. This minimizes the quota’s impact on the business, while still reaching the quota. Credits can be exchanged between businesses or bought and sold in international markets at the prevailing market price. There are currently two exchanges for carbon credits: the Chicago Climate Exchange and the European Climate Exchange.

The GHG data table as per United Nations Framework Convention on Climate Change(UNFCCC):-

CO2 – Carbon dioxideCH4 – MethaneN2O – Nitrous oxidePFCs – Perfluorocarbons HFCs – Hydrofluorocarbons SF6 – Sulphur hexafluoride

The Global Warming Potentials (GWP) used for presentation of CH4 and N2O in terms of CO2 equivalent are 21 and 310, respectively. That is if we reduce 1 ton emission of methane it is equivalent to reducing 21 tons of CO2 as such.

So now we are concerned of making people aware of the necessity to bring down the GHG much below 1990 base line. To execute this mission world wide , this new “CURRENCY”, Carbon Credit and to spread awareness of such a subsidy for Clean Development Mechanism (CDM).

The project is primarily aimed at making the non-conventional energy sources more familiar and to exploit the tremendous potential of wind power to the optimum thus creating a wide spread awareness among the people on the importance of non-conventional renewable energy source – wind. Wind Power Projects are eligible for availing Carbon Credit and are considered as Clean Development Mechanisms (CDM), and are bound to get immense popularity for its economical as well as environmental advantages. In this project we will design and build a small roof top mountable wind turbine.

Wind power is a clean, renewable source of energy which produces no carbon dioxide emissions or waste products. Individual turbines vary in size and power output from a few hundred watts to two or three megawatts. Uses ranges from very small turbines supplying energy for battery charging systems, to turbines on wind farms supplying electricity to the grid. We should consider the following issues if we’re thinking about small scale wind. Wind speed increases with height so it’s best to have the turbine high on a mast or tower. Generally speaking the ideal site is a smooth top hill with a flat, clear exposure, free from excessive turbulence. Small scale wind power is particularly suitable for remote off grid locations where conventional methods of supply are expensive or impractical. The turbine used is not conventional type which has three blades but instead we designed and constructed a turbine with eight blades. Ideally we should have done an assessment of the local wind speed for a at least a period of one year at the location of intended installation of Microwind. Also this procedure may be avoided because our prototype is not intended to work outdoor but is only for demonstration inside the workshop inside the college campus under induced wind. We tested the prototype, Microwind under induced wind using two pedestal fans inside the college workshop itself. The prototype passed the test and is found capable of charging a backup battery or may be integrated with a UPS system. The project “MICROWIND” is tested successfully and under the light of the success of this small prototype we could very well proceed with a larger model which is capable of providing supply to the whole campus in the very near future with no import of technology and we could very well develop our own MW wind turbine suitable for the terrain. The prototype with an AC generator produced an output of 50W.
