Tidal Power - Generating electricity from tidal currents - 1 views

  • It will generate one of the most environmentally-friendly forms of energy - it makes no noise
  • "But if we could harness 0.1 percent of the energy in the ocean, we could support the energy needs of 15 billion people

Global Fossil-Fuel CO2 Emissions - 1 views

  • Since 1751 approximately 337 billion tons of carbon have been released to the atmosphere from the consumption of fossil fuels and cement production
  • Half of these emissions have occurred since the mid 1970s

Tidal Power: Nature's renewable hydro electric engine: Additional info - 2 views

  • Tidal power energy is still being studied and developed, but in the future it could be a major renewable hydropower energy source.
  • England, for example, could supply over 10 percent of its electricity in this way.
  • . Wind and solar energy generators convert much less.
  • ...2 more annotations...
  • They can convert about 80 percent of the energy into electricity
  • Another disadvantage is that the start-up costs involved are very high and a lot of time is required for the construction projects, which can cost millions of dollars and take up to 10 years to build

EnergyBC: Tidal Power - 2 views

  • his is somewhat balanced out by long plant lives of 100 years for the actual barrage structure, and 40 for the equipment, as well as low operating costs.
  • An estimate is given by researcher Eleanor Denny. Denny estimates that in order for a facility to be profitable, its capital cost should be less than €530,000 (~$700,000 USD) per MegaWatt which with the current technology is not a realistic goal, meaning that so far the industry produces negative net benefits.50
  • Canada's Race Rocks site, where a single turbine generator converts 65 kW of energy, cost $4,000,000.54 This figure was met with $3,000,000 investment from project partner EnCana's Environmental Innovation Fund, and a grant of just under $1 million awarded to Pearson College and their partners in the project.

  • This plant produces about 100 times the power generated at Race Rocks. An investment of around €8.5 million ($11 million USD) made SeaGen a reality.
  • , they are, by nature, reliant on the natural environment and therefore are vulnerable to the effects of climate change
  • sustainable energy resources produce limited amounts of carbon dioxide emissions
  • The environmental impacts of tidal barrage include hampered fish migration, forced water level changes on the basin behind the barrage, reduced salinity in the basin due to low quantities of ocean water, and reduced ability of currents to transport and suspend sediments

Tidal Energy for Kids - 0 views

  • As far as producing electricity goes, tidal energy is one of the cheapest kinds.
  • Since the tidal cycle repeats itself every 24 hours, there is a guarantee that power can be produced this way every day of the year.
  • can help protect delicate coastal areas from storm damage, as well
  • ...4 more annotations...
  • can protect against erosion
  • Even though tidal energy does not produce any kind of pollution, the barrages completely change the coastline. Many animals and birds make their homes on the mudflats around tidal basins. When the tidal energy plants flood these areas, the habitats of these animals are destroyed. Holding the water back also causes silt to build up inside the tidal basin and can cause the released water to take longer to clear from dirt and materials. This can keep the water around the coastline from settling and becoming clear as quickly as it usually does. There is also evidence that using tidal power plants can change the migration patterns of many ocean creatures.
  • Other people think that since tidal energy plants can only produce electricity for about ten hours every day,
  • it is not worth the danger to plants, animals, and ecosystems.

What is tidal energy - How tidal works? - Tidal energy - 0 views

  • For producing significant amount of energy out of tidal water turbines, range of tides should be high and substantial amount of water should be there for pushing water through the turbine.
  • It is significantly important to spot the appropriate place which provide suitable and sustainable conditions to produce tidal energy, there are plenty of places around the globe which provide good conditions for installing water turbines and then produce electricity use tidal power of oceans in the location.
  • Once tidal power plant is built its’ electricity is free. It does not emit greenhouse gasses, carbon emission gasses which pollute environment. It does not have any dependency of any fossil fuel including furnace oil, gasses, etc; it needs no oil what so ever to produce electricity. Tidal power technology is renewable energy, which uses tidal and waves of same water for producing electricity over and over again. Tidal power technology like all renewable energy is clean energy and does not leave much impact on environment. Tidal power plants does not require much maintenance, therefore it is maintenance cost free. Tidal energy stations have about 80 % efficiency ratio, where as fossil fuel have approximately 30 % for efficiency levels. Tides in oceans are very predictable, its easy to judge when strong tides are going to show up from water consider weather and other conditions. The better tides and wave strengths of the oceans is, improved the efficiency of the station is. Electricity does not fluctuate on large scale using tidal energy as it happens in solar power technology.

  • Tidal power plants are not cost effective. Millions of dollars are utilized for developing tidal power which could provide electricity in Megawatts.
  • Electricity can only be produced when tides are high in the sea, once ocean is calm and does not flow certain level of waves, it cannot produce electricity. Therefore electricity can be produced for only 10 hrs a day in presence of tides.
