This rings true when talking about energy drinks. These products promise to provide heightened awareness‚ more energy‚ more endurance some even reference to the consumer you will have wings. So when consuming these products what are you really drinking? Do they provide the energy boost they promise? Are they harmful? Should the FDA do more investigating into the safety of these so-called energy drinks? These are questions I had going into this as a consumer of energy drinks myself‚ I was interested

* The sun has produced energy for billions of years. Solar energy is the sun’s rays (solar radiation) that reach the Earth. This energy can be converted into other forms of energy‚ such as heat and electricity. * In the 1830s‚ the British astronomer John Herschel famously used a solar thermal collector box (a device that absorbs sunlight to collect heat) to cook food during an expedition to Africa. Today‚ people use the sun’s energy for lots of things. solar energy can be used to: * Heat

Calculating Efficiency. Efficiency (%) = Useful Energy Out x 100 Total Energy In Questions 1) A light bulb takes in 30J of energy per second. It transfers 3J as useful light energy and 27J as heat energy. Calculate the efficiency. 2) A kettle takes in 2000J of energy per second. It transfers 1500J as useful heat energy and 500J is wasted as sound energy. Calculate the efficiency of the kettle. Remember: In the exam they may not

WAVE ENERGY Chapter 2: Energy Technology 2.1 Source of Wave Energy Ocean waves are caused by the wind as it blows across the open expanse of water‚ the gravitational pull from the sun and moon‚ and changes in atmospheric pressure‚ earthquakes etc. Waves created by the wind are the most common waves and the waves relevant for most wave energy technology. Wave energy conversion takes advantage of the ocean waves caused primarily by the interaction of winds with the ocean surface. Wave energy is an

$20 per Gallon Book report This is an amazing book about the effect of gasoline prices on the world. The author starts off by describing what happen in 2008 when the countries gas prices soared to historical highs $4 a gallon. Some people only look at the bad side of gas going up and never consider the good things that can come out of it. In this book the upside and downside of rising gasoline prices are examined‚ and I find out some surprising facts about gasoline prices rising. For instance

Physics Energy Exploration Project Energy can be stored in many forms as potential energy. It can be extracted through chemical and mechanical processes to get usable energy. We use that kinetic energy and electricity every day to power our lights‚ run our cars and do most of our tasks. Fossil Fuel is a non-renewable energy source. It results from the decomposition of dead and buried organisms. They are millions of years old and are fossilized under rock and sand. They are efficient energy producers
