Biomass-Advantages and Disadvantages

Biomass - Important facts Biomass advantages and disadvantages are associated with some very important facts. Day by day the conventional energy sources like fossil fuels is reducing. Finding sources for conventional energy is a very complicated and lengthy process. But with the increasing population, the need for new energy sources is also rapidly increasing in developing countries and in

Pros and Cons of Solar Energy

The energy from the sun reaching the earth per day ranges from about 600 Btu (British Thermal Unit) / square feet for Northern Europe to about 2000 Btu/square feet for arid regions near the equator. More energy from sun strikes the earth in one hour than all energy consumed on the planet in a year! A summer day’s sun at noon provides a square, meter of land with a power input almost a kilowatt.

Impact of Renewable Energy Sources on Global Warming in India

A brief story of global warming- global warming skepticism Of all the forecasts of global environmental disasters made from time to time, the one which aroused the most widespread skepticism was about global warming. Even as several well-meaning people took it seriously- some rather too seriously- a whole lot of other scientists and policy-makers dismissed it as over-exaggeration. During

Non-tracking Concentrators Classification and Working Principles

Tracking concentrators provide high delivery temperatures but require accurate tracking device and fine surface accuracies and hence are expensive. However, for medium temperature operation, less expensive concentrators have been designed, without the tracking required. The description of some of these concentrators is given below: Classification of Non-Tracking Concentrators Broad

Construction and Working Principle of Two-axes tracking Concentrators

In order to achieve a high concentration for high temperatures solar processes, concentrators with double curvatures are used. These requires two axes tracking of the sun. Some of these have been described below: Please Read: One axis tracking concentrator classification, construction and working principle Elaborate classification, advantages and disadvantages of solar concentrators

One-axis tracking concentrator: classifications: working Principles

Concentrators with one axis tracking are used to achieve moderate concentration. A few of them have been described below. Please read: Classification, construction and working principle of two-axes tracking concentrator Classification and Working Principle of non tracking solar concentrators For knowing about the other concentrators follow the link: Classification of Solar

Solar Concentrator Classification: Advantages of Solar Concentrator

Introduction: Definition of Solar Concentrators: Solar Concentrator is a device which concentrates the solar energy incident over a large surface onto a smaller surface. The concentration is achieved by the use of suitable reflecting or refracting elements, which results in a increased flux density on the absorber surface compared to that existing on the concentrator aperture. In order to

Renewable Energy Sources: The Great Green Hope for clean environment

Fossil fuel use is the prime cause of global warming and ocean acidification. Then the obvious solution to that problem is that: Either some way is found out to use fossil fuels, but not let the resulting CO2 escape to the atmosphere, in other words to sequester (catch/lock up) the CO2 , or To find other fuels which do not release CO2 (or other greenhouse gases) Renewable Energy Sources

Solar Air Heater Classification and Advantages

This post provides the description and analysis of different types of solar air heaters used in space heating and drying purposes. The Solar air heaters have the following advantages over other solar heat collectors. Solar Air Heater Advantages The need to transfer heat from working fluids to another fluid is eliminated as air is being used directly as the working substance. The system

Solar pond pump-features of solar fountain pump

What is a solar pond pump? A solar pond pump takes the solar energy from a PV or Photovoltaic panel. Sometimes these pumps are designed as a fountain and sometimes called the solar fountain pump. A solar powered pond pump can be a great alternative to the conventional pumps. And eventually in the long run it will save the expenses. For the perfect functioning of solar pumps the solar
