The Pros And Cons Of Tidal Power

982 Words4 Pages

Tidal power has been exploited by mankind since 900 A.D for variety of uses. Most uses of tidal power in its early days, involved in conversion of potential energy into mechanical energy rather than to electrical energy like how it’s being used today (Tidal.Inc, n.d). By building a barrage over an open basin and allowing it to fill up by the rising tide, then flowing the collected water over a water flywheel or a similar energy conversion device generated enough power to operate basic machines such as flour grinder and more (Tidal.Inc, n.d).
It was at 1960’s the first commercial scale modern-era tidal power plant was built in France for electric power generation. The plant was equipped with twenty-four turbine generators and operated for thirty-seven years (Tidal.Inc, n.d). Since then, numerous studies had been conducted on tidal powers whopping nearly 100 million US dollars, to optimise the energy to the fullest. Waves
The friction between blowing wind of the ocean and the water surface is known to generate waves. Wave heights are can differ depending on the speed, duration of the wind and the topography of the ocean floor. The streaming water from higher to lower …show more content…

Tidal energy benefits as it is a renewable energy as it is the result of gravitational field from both moon and sun combined with earth’s rotation resulting in high and low tide (Energy Informative, 2013). Tidal energy is also easy to be predicted as tidal currents are highly predictable (Tidal Power.UK, n.d). This makes it easier for engineers to construct a system which is highly effective. Thirdly, tidal power is also effective in low speed. As water is 830 times denser than air, it’s calculated that electric can be generated even with the flow of 1 m/s (Energy Informative, 2013). Also, tidal power plants have long lifespan, as the barrage in La Rance has been operating since 1966 (Tidal Power.UK, n.d). This makes it cheaper to operate in long

Factors Affecting Nashville's Physiographic Regions

767 Words | 4 Pages

On a sunny day, the land absorbs heat from the sun more quickly than the water does. The air over the land becomes warmer as some of this absorbed heat is radiated back into the air. The warmer air begins to rise, and the cooler air over the water moves in to take its place. At nighttime when the sun goes down, the land cools off quickly, but the water does not. The water radiates some of its stored heat into the air, and this warmed air begins to rise.

Pros And Cons Of The Keystone XL Pipeline

2026 Words | 9 Pages

It uses flowing water to generate electricity. It does this by using dams and reservoirs for storage. This method gives us the most electricity rather than any other renewable energy source. Not only do the dams and reservoirs create electricity, they also control flooding (Sambu). Hydropower is the least expensive procedure to generate electricity.

Compare And Contrast Solar And Solar Energy

1168 Words | 5 Pages

wind energy and solar energy are both renewable types of energy they create no pollution and are fully sustainable as they are both powered by natural sources and if there is no wind one day the solar panels can generate energy and if it 's cloudy another day the windmills can generate energy also the energy created during the summer can be sold to the grid for extra capital that can be used for field trips, renovations, etc. Geothermal heating systems are rated the most efficient and eco-friendly heating systems. The system works using buried coils that contain a liquid, typically a mix of water and antifreeze. The liquid is warmed to the same temperature as the earth and then runs through to the home where a compressor extracts the heat but not only that geothermal heating requires no fossil fuels so it is very eco-friendly LED lighting is an efficient and eco friendly lighting alternative because they waste much less energy in converting to light compare to incandescent lights which waste 90% of the energy to convert to heat not only that LED lights last up to 15-25 times longer that traditional light bulbs this makes LED a much better source of lights than others because it wastes less energy and it is more efficient at doing its job this is so much better for the environment because it uses less energy that other lighting sources

Nowadays, we usually use the newer term called “wind turbine”.1 About four percent of the energy created in the United States comes from wind energy,2 and over 100 countries are now following in this trend and produce energy through the use of wind. This not only shows that a wind energy has great potential in the future, but also how popular it already is. It can be said that the more countries there are that using wind energy the better it is for our world. It is better because wind energy is a sustainable energy source.3 Looking back already at around 1000 AD wind power used and spread around northern Europe, starting with Holland.
