Water-Saving Ideas for Schools Free Repair leaky faucets and toilets throughout the school building. Encourage maintenance staff to avoid using hoses or pressure washers to clean sidewalks and other paved areas. Never allow water to run unnecessarily‚ and avoid using the toilet as a trash can. Avoid overuse of the air conditioning – the harder it works‚ the more water (and energy!) is used to cool the building. Encourage your school’s cafeteria staff to avoid

attempted to solve the questions of‚ “How polluted is U-High’s stream?” and‚ “How can water quality be measured?” They initially believed the creek to be of good quality. Many organisms within the water rely on dissolved oxygen‚ including fish‚ macroinvertebrates‚ and oxygen. Fish and macroinvertebrates use dissolved oxygen to breathe through their gills and bacteria relies on dissolved oxygen to decompose dead organisms. Dissolved oxygen is oxygen that has water molecules mixed in as a result of the

Michael Marder’s article “Our polluted senses” on The New York Times expresses the author’s preoccupation about the urban life where noise‚ light‚ flavor‚ and scent pollution are “assaulting” our sensories. As an urban citizen‚ I completely agree with the author for what artificial factors are exacerbating the quality of life. The overwhelming presence of industrial revolution restrains us from utterly perceive the world. Bright lights on the street‚ the resplendence coming from skyscrapers‚ metropolitan

“Solar Treated Purification” Intorduction: A. Background of the study: In our world today‚ purified water is the one that most of the people drink everyday especially those who live in cities. Water purification is the process of removing undesirable chemicals‚ biological contaminants‚ suspended solids and gases from contaminated water. The goal is to produce water fit for a specific purpose. Most water is purified for human consumption (drinking water)‚ but water purification may also be designed

A solar inverter‚ or PV inverter‚ converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequencyalternating current (AC) that can be fed into a commercial electrical grid or used by a local‚ off-grid electrical network. It is a critical component in a photovoltaic system‚ allowing the use of ordinary commercial appliances. Solar inverters have special functions adapted for use with photovoltaic arrays‚ including maximum power point tracking and anti-islanding protection

Save Water You can lower the temperature setting on your water heater and save money at the same time by insulating your water pipes. Just insulating the hot water pipes can reduce heat loss and raise your hot water temperature by 2-4 degrees F. You will save water as well‚ as it won’t take as long for the water to heat up. As you can see‚ there are many different types of “green energy” technologies. Because there are so many options‚ there is bound to be a way to put "green energy" to work for

The researchers were able to gather information from different journals and newspapers that already featured the solar panel. Moreover‚ they indicate information that was gathered from the internet. This study used descriptive method of research because the researchers aim to elaborate all the features of solar panel. The study was designed to give knowledge on the use of solar panel

This article is about all uses of solar energy. For the journal‚ see Solar Energy Journal. The 19.9 MW Gemasolar solar plant in Spain features 15 hours of storage and can supply power 24 hours a day. Solar energy‚ radiant light and heat from the sun‚ has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar energy technologies include solar heating‚ solar photovoltaics‚ solar thermal electricity‚ solar architecture and artificial photosynthesis‚ which

Acid Rain Acid rain is polluted rain. The pollutants go up to the atmosphere and when it rains it brings the pollution down with it. Sulfur dioxide and nitrogen oxide are the gases that form the acid rain. When these gases mix with moisture it can make rain‚ snow‚ hail‚ or even fog. The scientific term for acid rain is acid deposition which means when the acid is taken from the air and is deposited on the earth. Major industries‚ coal burning factories‚ power plants and automoble engines
