Renewable energy Renewable energy is any source of energy that doesn ’t consume the finite resources of the Earth and can be easily and quickly replenished. At present only a small proportion of the world ’s energy needs come from alternative and renewable energy sources. These exist in many forms including Solar Thermal‚ Photovoltaics‚ Wind‚ Hydro‚ Tidal/Wave and Bioenergy (including Biomass‚ Biogas and Biofuels). As with fossil fuels the sun ’s energy is the ultimate source of these energies.

Types of Energy: Energy is the ability to do work and there are many types of energy. Mechanical Energy is the energy of motion that does the work like the wind turns a windmill. In physics‚ mechanical energy is the sum of potential energy and kinetic energy present in the components of a mechanical system. It is the energy associated with the motion and position of an object. The law of conservation of energy states that in an isolated system that is only subject to conservative forces‚ like

Essay on Energy Drinks should be Banned A few months ago‚ the analytical and research agency Packaged Facts (PF) noted a sharp increase in the demand for energy drinks. According to the PF experts‚ the revenue from the sales of this category of products will exceed $21.5 billion by 2017. For comparison‚ the legendary Coca-Cola Corporation‚ providing water dispensers all over the world‚ earns about $47 billion annually. However‚ this week‚ the popular energy drinks industry attracted attention

Experiment 1: Heat Capacity of Gases 1. BACKGROUND The first law of thermodynamics can be illustrated particularly well with an ideal gas. This law describes the relationship between the change in internal intrinsic energy ΔUi the heat exchanged with the surroundings ΔQ and the constant-pressure change pdV. dQ = dUi + pdV (1) The molar heat capacity C of a substance results from the amount of absorbed heat and the temperature change per mole:
