Frequently Asked Questions About… Department of the Environment Compact Fluorescent Light Bulbs What are the benefits of compact fluorescent light bulbs? Compact fluorescent light bulbs (CFLs) have several advantages over incandescent light bulbs. They last 810 times longer‚ use about 75% less energy‚ and produce 90% less heat while delivering more light per watt. For example‚ a 25-watt CFL provides about 1800 lumens‚ compared to 1750 lumens from a 100-watt incandescent lamp. Use of CFLs reduces

switch from incandescent light bulbs to compact fluorescent light bulbs. When an incandescent light bulb is turned on‚ only ten percent of the electricity used is turned into light. The other ninety percent is wasted as heat. On the other hand‚ compact fluorescent light bulbs use seventy to seventy-five percent less energy than incandescent light bulbs and they last up to ten times longer than incandescent bulbs. For instance‚ by using a 26-watt compact fluorescent light bulb‚ which is equivalent

1. Choosing the text Both Harmer and Scrivener are very direct with their advice for choosing texts for reading and listening: Grade the tasks‚ not the material. Despite keeping this in mind I felt anxious about possibly choosing an authentic text that would be discouraging for our group of elementary-level students due to its complexity. I settled on a list of tips for saving energy published on the National Geographic Kids website (see Appendix 1). I chose this text because we have

Pollution and its Negative Effects Pollution is the degradation of natural environment by external substances introduced directly or indirectly. Human health‚ ecosystem quality and aquatic and terrestrial biodiversity may be affected and altered permanently by pollution. Pollution occurs when ecosystems can not get rid of substances introduced into the environment. The critical threshold of its ability to naturally eliminate substances is compromised and the balance of the ecosystem is broken.

Conservation of Natural Resources Introduction: Humans have always made use of other species. Most wild species are found in areas where people live. This is either because people want to gather natural resources from there or they put their life to risk for purpose. Over the last 10‚ 000 years our food has come increasingly from cultivated plants and animals. This has resulted in the rapid increase in human population. The wise and smart use of the earth’s resources by humanity is termed as
