Solar Energy: Powering Our Future Today nearly half of the world’s energy is provided by petroleum. What began as a cheap and abundant way to provide energy‚ has become expensive‚ environmentally harmful‚ and finite. With population explosions and the demands of modern lifestyles‚ the world’s need for energy production has become far too much for fossil fuels to keep up with. Experts say that the Earth’s stores of petroleum will be depleted by 2050. The need to find a viable source of energy within

WHAT IS TORQUE? Torque is a measure of how much a force acting on an object causes that object to rotate. The object rotates about an axis‚ which we will call the pivot point‚ and will label ’O ’. We will call the force ’F ’. The distance from the pivot point to the point where the force acts is called the moment arm‚ and is denoted by ’r ’. Note that this distance‚ ’r ’‚ is also a vector‚ and points from the axis of rotation to the point where the force acts. (Refer to Figure 1 for a pictoral

Analyse how the cardiovascular and the digestive system interrelate to perform energy metabolism. Energy is used up all the time for body processes. Energy starts at conception and continues to carry on until you die. The amount of energy you need depends upon your age‚ sex and your level of activity. Food provides the energy we use; our foods bring us the vital energy that our body is burning throughout the day. Body growth‚ development and functioning are some of the vital and fundamental aspects

ENERGY SAVING FACT SHEET Introduction Central building cooling options include water chillers and direct-expansion (DX) A/C units. Chillers use a refrigeration cycle to cool water to 42º F to 55º F for pumping to chilled water cooling coils. Air is then blown over the chilled water cooling coils to provide cool air to the conditioned space. DX systems also use a refrigeration cycle‚ but distribute refrigerant directly to DX cooling coils – some are packaged in a single housing‚ others are split

PROTEIN ENERGY MALNUTRION Types include:[2] * Kwashiorkor (protein malnutrition predominant) * Marasmus (deficiency in both calorie and protein nutrition) * Marasmic Kwashiorkor (marked protein deficiency and marked calorie insufficiency signs present‚ sometimes referred to as the most severe form of malnutrition) Note that this may also be secondary to other conditions such as chronic renal disease[3] or cancer cachexia[4] in which protein energy wasting may occur.

Energy Drinks Many energy drinks are found in the market and many people are consuming them without knowing the bad effects on their health‚ having the misconception that they help in enhancing and boosting the body energy. Ingredients: Other than the caffeine and carbohydrates energy drinks contain: B vitamins: Energy drinks contain B vitamins that exceed the daily-recommended amounts. Gingko: German pharmacological studies suggest that this herb increases blood flow to the brain

The Economics of Renewable Energy in Kenya 1.0 BACKGROUND 1.1 Introduction The Kenyan economy will increasingly feel the impact of the Government’s commitment to reducing carbon emissions‚ including targets for greater use of energy from renewable sources. The Government describes its targets for renewable as challenging; others have suggested they are unachievable. In any event‚ the effort to meet them will come at a cost and‚ if not properly managed‚ risks distracting attention from other

today’s climate of growing energy needs‚ it is imperative to find sources of renewable or limitless energy. There is a plentiful amount of fossil fuels‚ including coal‚ natural gas‚ and oil. It remains to been seen however‚ if these resources can be depended on in the future. According to the United States Energy Information Administration‚ the U.S. “is the birthplace to some of the word’s greatest clean energy technology”‚ but produces less than half of Germany’s clean energy program. In the last

from various kind of informative books i borrowed are: A wind turbine is a product that converts wind energy into electrical energy that is use to distribute to the homes of people. Benefits of a wind turbine: It does not release any harmful gases into the air when powered and it is also affordable in many different countries for supplying electricity to homes‚ by converting the wind energy to electricity for distribution. A hydropower is a production of electrical power through the use of
