The solar energy use in Africa These days‚ solar energy has been the most talkative alternative energy source in the world. Unlike the gas‚ oil‚ and coal‚ solar enrgy is one of the clean and renewable resource‚ which can not only generate power but also protect the environment. Africa‚ has second largest population‚ estimated 1.6 billion‚ however‚ around one third of it’s people still live in the condition with no eletricity. (Renewable energy in Africa

ummary: Did you ever think that how the street lights automatically turn ON in the night and turn OFF automatically at morning? Is there any person who comes to ON/OFF these lights? The following circuit that described below which perform this job automatically. This circuit employed the output from an uncomplicated light/dark activated circuit and oblige a relay in its output which can be further attached to switch ON/OFF a street light and electrical application in a household also. Many of the

Project Tiger was launched by Kailash Sankhala in India in 1973. The project aims at ensuring a viable population of Bengal tigers in their natural habitats and also to protect them from extinction‚ and preserving areas of biological importance as a natural heritage forever represented as close as possible the diversity of ecosystems across the tiger ’s distribution in the country. The project ’s task force visualized these tiger reserves as breeding nuclei‚ from which surplus animals would migrate

Conserve Energy Carmen Salyer SCI275 Conserve Energy Conserving energy is very important to our generation and future generations as well. By conserving energy we also help slow down the process of global warming and lower the pollutants in the air that we consume on a daily basis. This is why we need to conserve the energy that we have today. We should use renewable sources or sources that are renewed at the same rate they are used such as wind power‚ solar power‚ hydropower and biomass

Daylight-Saving Time has been a controversial issue for the United States since it was adopted in 1966 (“Extra!: Daylight-Saving Time”). From the beginning Congress has had difficulties with the length‚ start date‚ and time of year that Daylight-Saving Time occurs. Though Congress has had problems with Daylight-Saving Time both now and in the past it is still hard to determine whether Daylight-Savings is for the greater good of the country or if it is an unneeded hassle. By examining the effects

Li‚ 1 2-16-13 Solar Energy: The Energy of the Future Our Earth’s resorvoir of resources seem to be limitless‚ but with the exponential growth of the human population; the need for efficient alternative energy sources is becoming urgent. Therefore‚ research companies and individuals are focusing on creating new energy systems. Fossil fuels are are depleting and becoming more difficult to obtain. The earth will face an energy crisis in the near future if humans are not careful with their consumption

Examples of Radiant Energy The term radiant energy refers to energy that travels by waves or particles‚ particularly electromagnetic radiation such as heat or x-rays. Radiant energy is created through electromagnetic waves and was discovered in 1885 by Sir William Crookes. Fields in which this terminology is most often used are telecommunications‚ heating‚ radiometry‚ lighting‚ and in terms of energy created from the sun. Radiant energy is measured in joules.

Light Pollution 1. Every urbanite knows the bright lights of the city make it impossible to see the stars in a night sky. What most of us do not know is that those lights also may be making us sick. The cause is light pollution – the unearthly glow of billions of street lamps‚ security and porch lights‚ searchlights‚ office lights and signs – as people everywhere try to dispel the darkness of the night. 2. For the first time‚ light is being investigated seriously as a pollutant and a health hazard

The Gorillas are hunted and poached in many different parts of the world (mainly in Congo‚ Africa)‚ often to sell their body parts as souvenirs. Most people many find it crazy to think of such a thing to hunt such a beautiful and ferocious

ENERGY RESOURCE PLAN Conserving energy is important to our society because it can extend the life time of non-renewable resources. Examples of these are oils‚ coal ‚ and gas. It also minimizes the use of larger more dangerous and environmentally damaging sources ‚such as deep sea oil and tar deposits. Currently the world produces 20 million barrels of oil each year. One-third of that is used by the United Sates. Concidering that only %35 of an oil well can be recoverd one-third is a lot to consume
