Fossils Fuels vs. Renewable Energy | Ecology Global Network - 1 views

  • Burning fossil fuels creates carbon dioxide, the number one greenhouse gas contributing to global warming. Combustion of these fossil fuels is considered to be the largest contributing factor to the release of greenhouse gases into the atmosphere. In the 20th century, the average temperature of Earth rose 1 degree Fahrenheit (1°F). This was a period that saw the most prolific population growth and industrial development
  • Some estimates say our fossil fuel reserves will be depleted within 50 years, while others say it will be 100-120 years.
  • Sun, wind and water are perfect energy sources…depending on where you are. They are non-polluting, renewable and efficient

  • The object is to capture and harness their mechanical power and convert it to electricity in the most effective and productive manner possible.
  • Another form of hydroelectric energy is tidal power. In use since the early 1900s, tidal power stations collect the energy created by the rise and fall of the tides to convert to electricity.

Kinetic energy - Wikipedia, the free encyclopedia - 0 views

  • The kinetic energy of an object is the energy which it possesses due to its motion.[1] It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body in decelerating from its current speed to a state of rest.

Wave & Tidal Energy | Market | BioPower Systems - 0 views

  • The growth of the waves depends on the strength of the wind, its duration, and the open ocean distance (fetch) over which it blows
  • Ocean waves are created by surface winds.

Wave power: how it works | SmartPlanet - 0 views

  • What is wave power? Wave power is renewable energy derived from ocean waves. It is the kinetic energy of wind interacting with water and creating waves
  • Wave energy is generated by the wind
  • The best wave energy environments are along western coastlines because the largest, most consistent winds come from the west,
  • ...7 more annotations...
  • How does wave power work? Most of the energy comes from the rising and falling water level and requires exposure to the waves
  • There might never be a dominant technology for harnessing this power
  • because of the differences in potential wave energy sites throughout the world.
  • all ocean energy resources, including wave power, would combine to create energy 800 times more powerful than wind
  • Currently, wind is our biggest renewable energy source
  • What are the benefits of wave power? Because wave devices tend to be on the surface and don’t have propellers, as tidal power technologies do, some believe they will create less environmental damage than other renewable energy technologies,
  • There are advantages compared to wind in that the devices are smaller and don’t have the visual profile that wind turbines have.”
