Renewable Energy - Renewable Energy Energy cannot be created or destroyed, but it can be transformed: the first law of conservation of energy. Since the earliest days of human history, man have always been looking forward to control energy. But it wasn't until the nineteenth and twentieth centuries that humanity finally learned to harness the high concentration of energy existent in fossil fuels. ('Why Sustainable Energy Matters,'Learning Space). Even though humans achieved to apply the first law of conservation of energy/matter, they failed to understand the principle....   [tags: Energy ]

Converting Energy - Converting Energy 1 The Law of Conservation of Energy states that energy can neither be destroyed or created, only transferred or transformed. That being said, each form of energy has the ability to be converted into another form of energy. And since there are several forms of energy, that makes many different conversions achievable. Almost all technological gadgets convert one energy form into a new one. The vast number of devices that can convert energy into other states of energy are termed transducers....   [tags: Energy]

Energy Transmission - In energy systems where the energy-collection process in an energy-material is needed as a step physically separated from the Processing Unit, the transportation of the energy-material that contains the energy is required. In the case of biomass-based energy systems, this step encompasses all the infra-structure associated with the logistics of supplying biomass to the Processing Unit: machines, roads, pipes, etc. Although the energy that flows through this stage is tied to the amount of raw material demanded by the processing plant, its cost structure may vary freely, dependent upon the type of transportation technology adopted (i.e.: pipelines, trucks, railroads), distances, daily demand of the processing unit, operation time, and physical characteristics of the raw material (as density)....   [tags: Energy] 869 words

Renewable Energy - Renewable energy is a term used to describe a source of energy that has the capability to refill itself. Renewable energy is sometimes called infinite energy. Renewable energy is also known as green or clean energy, because it does not produce toxins or pollutants that are harmful and dangerous to the environment. Planet earth is going on a critical phase, due to the fossil fuels being consumed worldwide every day. Jimmy Carter once stated on a televised in April 18, 1977 that "Because we are now running out of gas and oil, we must prepare quickly for a third change, to strict conservation and to the use of coal and permanent renewable energy sources, like solar power." Slowly and gradually those fossil energies would reach their ends, because they are quite limited....   [tags: Energy ]

Sustainable Energy Systems And Their Benefits - In recent years the research of scientists has come to public attention and it is a widely accepted fact that the Earth is warming up. What has caused this change in the Earth is still up for debate and a controversial issue. One side is that humans are causing the warming by burning fossil fuels. Staying on that topic, fossil fuels are limited in quantity, and some scientists speculate that we may run out sooner than we are ready for. This is where sustainable energy systems come into play. When using sustainable energy systems such as hydro electric, wind, or cruder methods such as waste incineration, burning of fossil fuels will decrease....   [tags: Energy]

Nuclear Power: Energy for the Future - Nuclear power is a technology synonymous with extirpate, radiation, health issues, and instability, but also mass energy production. Nuclear power has many common misconceptions, like these, and is often seen as a large risk. But rest assured nuclear power is the cleanest most immaculate way to power our growing nation, despite skepticism about safety concerns. Nuclear power is a way of harnessing the great power released by a nuclear fission reaction. Nuclear fission is, “an extremely complex nuclear reaction representing a cataclysmic division of an atomic nucleus into two nuclei of comparable mass....   [tags: Energy ]

Hawaii’s Renewable Energy Future - “By 2020, Hawaii is aiming to generate 20 percent of its energy from non-fossil fuels” (Brown et al. 2008, 11). According to the National Renewable Energy Laboratory (Arent et al. 2009, 1-2), petroleum accounts for 90% of Hawaii’s energy consumption and 75% of their electricity. Since Hawaii has no pipelines or oil fields, they are forced to import petroleum to accommodate their energy needs (Arent et al. 2009, 1). Hawaii is disconnected from the rest of the United States, which means that Hawaii has to take care of its own energy needs (Croucher 2010, 79).How can alternative energy sources reduce the need to import of petroleum....   [tags: Energy ]
