whole world. CO2e? What’s that? Man-made climate change‚ or global warming‚ is caused by the release of certain types of gas into the atmosphere. The dominant man-made greenhouse gas is carbon dioxide (CO2)‚ which is emitted whenever we burn fossil fuels in homes‚ factories or power stations. But other greenhouse gases are also important. Methane (CH4)‚ for example‚ which is emitted mainly by agriculture and landfill sites‚ is 25 times more potent per kilogram than CO2. Even more potent but emitted

It also aimed to use crude extract as fuel for lighting purposes. The study was limited to the extraction of crude from yellow bell seeds and its possible use as fuel for lighting purposes. The extraction did not use any organic solvent—only water. Chemical analysis of the crude extract was not done. There was no statistical treat-ment needed‚ only the

an Alternative Fuel Source Objectives: This study aims to compare the effectiveness of a paper charcoal and a wood charcoal in producing fire. It specifically aims to determine: 1. Which can last longer between the paper charcoal and wood charcoal as fuel source. 2. Which is more effective to use as a fuel source. Hypothesis: There is no significant difference between the paper charcoal and the wood charcoal as an alternative fuel source. Scope and
