Biofuels Coal and crude oil are non-renewable resources. They take so long to form that they cannot be replaced once they have all been used up. This means that these fossil fuels are likely to become more expensive as they begin to run out. Petrol‚ diesel and other fuels produced from crude oil make a range of harmful substances when they are burned‚ including: carbon dioxide carbon monoxide water vapour particulates (solid particles) sulfur dioxide oxides of nitrogen or NOx.

According to the National Geographic Magazine‚ the use of solar polar or photovoltaic cells has surged at about 20 percent a year over the past 15 years. This is thanks to rapidly falling prices and gains in efficiency. Countries such as Japan‚ Germany and the United States are major markets for solar cells. With tax incentives‚ solar electricity can often pay for itself in five to ten years. (National Geographic) With this fact in mind‚ it is no wonder that the city of Massachusetts politicians

Solar car design Originally published on Solar Love. Generally speaking‚ I don’t think solar-powered cars are very practical. They are fun and do highlight how far we’ve come. They may help to advance certain electric car technologies and designs. However‚ except for certain niche situations (like a hospital car for rural Zimbabwe)‚ they have serious limitations. For one‚ solar panels aren’t cheap — risking their destruction or damage in a car accident doesn’t seem wise. Secondly‚ the sun

output power. Iterative simulation based software and EL images have been used to estimate series resistance of each cell. II. INTRODUCTION After the fabrication of a high power photovoltaic (PV) module‚ the most critical aspect is the duration for which the module can produce useful power. Reliability and lifetime of photovoltaic (PV) modules are key factors to system performance and warranty and thus are extremely important as far as PV business is concerned. Due to time constraints‚ accelerating aging

Located along the south eastern coast of Bangladesh‚ the island is 50 kilometres long and 5.15 kilometres wide. There are 15 unions in Sandwip.Because of its position and inaccessibility there is no possibility of grid electrification service in this area in the distant future. Sandwip is an upazilla with very
