Hydroelectric Energy

Is hydroelectric energy a good thing? What would happen if the dam breaks or cracks? Hydroelectric energy generates 10% of the nation’s energy. Although hydroelectric energy is renewable it is also a very clean energy and it doesn't create air pollution. What will happen when it is put into more cities and towns?

Hydroelectric dams can be built wherever there is some sort of body of water. Also the US is the 2nd largest user of hydroelectric energy. This energy is made by gathering the gravitational force of the moving water. The water turns the turbines and creates energy. Even though hydroelectric energy does not put any toxic byproducts into the air, however rivers can pick up clay and sand and can decrease the amount of fish that would live there. There are many impacts that this energy makes on the area that this is used on.

So lets think about that first question. Is hydroelectric energy really a good thing?  The energy won’t always be used of course. At night everyone is asleep and it doesn’t need to be used. So the process won’t be a constant thing to worry about. So what do you think about this energy? Would you use it in your community?

Geothermal Energy- The New Energy?

Geothermal Energy is obtained through being drilled from the ground. The heat and steam that comes from the inner areas of the Earth, are so strong, they can turn a turbine, creating energy and electricity. This is completely natural energy, nature made.

The energy’s creation is dominated by the United States, especially in the San Francisco and California area. Also, Iceland has over 25 active volcanoes, making it simple to produce Geothermal Energy in Iceland. Over 20 countries produce Geothermal Energy as well. This energy is not renewable, because while it is created, the water within is lost to evaporation. The recent technological advancements within Geothermal Energy, especially in the power plants of Geothermal Energy, makes an incredibly sufficient energy.

Can this be THE energy to power our city?

Solar Energy

Solar energy is generated by the sun. Basically most energies get there source from the sun. Green plants collect the sunlight and then convert it into water and carbon dioxide. Then people and animals breathe that in and that's where people get there energy from to perform work. The solar energy heats a fluid which powers a small stirling engine that generates electricity. Prices for photovoltaic (PV) cells are decreasing because they are being used more. PV cells go way back and were used in the 1950s on satellites. The efficiency went from 6% to 11% in just a few months. In the early 2000s the contribution of PVs to the global energy supply was growing rapidly. Solar energy does not produce harmful pollutants. Scientist have developed experimental PV cells that convert over 40% of the light that they receive into usable power.

One of the first uses of solar energy was the Roman bathhouses built in the first century which worked like a greenhouse letting sunlight through the south-facing walls. Although we have grown in how we use solar power since the first century scientists  still uses solar power today but known as concentrated solar thermal systems the popularity of solar power has long been based on its economy and as a renewable alternative to the nonrenewable use of fossil fuels to generate electricity. With global warming, the use of solar power has become

even more attractive, as it does not generate carbon dioxide.  A solar panel is made up of many photovoltaic cells. The collective power produced by an array of solar panels, such as are found on a house roof, can supply at least some of the building’s electricity needs.

In such cells, a small electric voltage is generated when light strikes the junction between a metal and a semiconductor (such as silicon) or the junction between two different semiconductors. The power generated by a single photovoltaic cell is typically only about

two watts.

Nuclear Energy

Information about nuclear energy: Nuclear power is a valuable source of energy in many places around the world. Nuclear Energy results from a reaction that takes place in the nucleus of an atom. After World War 2, nuclear reactors were used primarily for research and plutonium production in the beginning. Nuclear Energy has been a reliable source of energy in different parts of the world since the 1950s. Two main types of nuclear reactions that release energy are known as fission and  Some pros are that it is available almost anywhere. Also like it said in the information it has no pollution so you can continue living knowing that they’re also giving back to the environment, if you use Hydrogen energy. Some cons are that to be able to use the energy you have to make it which is very expensive to do. Lastly it is highly flammable so while it is in the making process the plants have to be very careful while making so no accidents happen. Hydrogen energy is a very available, reliable source. they’re also giving back to the environment, if you use Hydrogen energy. Some cons are that to be able to use the energy you have to make it which is very expensive to do. Lastly it is highly flammable so while it is in the making process the plants have to be very careful while making so no accidents happen. Hydrogen energy is a very available, reliable source.

Hydrogen Energy

Everyone has heard of the word hydrogen energy but what is it? Hydrogen is a fuel cell that combines hydrogen and oxygen to produce electricity, heat, and water. Fuel cells are often compared to batteries. Both convert the energy produced by a

chemical reaction into usable electric power. Hydrogen is 75% of the earth’s mass so it’s easy to find, although it is only the easiest to find in certain cities. Hydrogen is also odorless, colorless, tasteless and has little to none polluting emissions.

Although Hydrogen energy seems to be a very good thing to use there are also some cons. Some pros are that it is available almost anywhere. Also like it said in the information it has no pollution so you can continue living knowing that they’re also giving back to the environment, if you use Hydrogen energy. Some cons are that to be able to use the energy you have to make it which is very expensive to do. Lastly it is highly flammable so while it is in the making process the plants have to be very careful while making so no accidents happen.

The Scoop on Coal

Coal is one of the easiest resources to collect because it can be found on all the continents but is it safe to use? Our research done in the media hub shows that while it is an abundant source of energy it releases lots of harmful things like soot, CO2, and sulfur. It also degrades farmland & creates acid rain. Coal is mainly used to produce electricity for power plants but in the twelfth century it was mainly used to smelt metals.  It is a fossil fuel meaning that it can run out in our lifetime but eventually it would return. Coal is made from plants that have degraded and were compacted by all of the rock. One of the reasons coal releases so much heat energy is because while it was a plant it stored lots of sunlight and when burnt it releases all of the sunlight it had stored. Coal is classified in ranks, or types, according to the amount of heat it produces. The ranks are Lignite, Sub-Bituminous, and Bituminous. Lignite is the softest and it contains the most moisture while releasing the least carbon. Then Sub-Bituminous which has less moisture but releases a little more carbon than Lignite. Then finally there is Bituminous which has no moisture and releases large amounts of carbon.

Wind Energy

When air is warmed, it rises and is replaced by cooler air, leaving a low-pressure area that causes the movement of air known as wind. Windmills are the big things you see when you drive by a field. Windmills are a device that captures the energy of winds. They way windmills work is that the wind strikes the  the blades of a windmill, causing them to turn, and the solar energy stored in wind is converted to the kinetic energy of moving blades. That energy, in turn, is used to turn an axle, to power a pump, to run a mill, or to perform some other function. The amount of power that can be converted by a windmill depends primarily on two factors: the area swept out by the windmill blade and the wind speed. The questions we ask yourself is how does this contribute to us, and how do we keep the wildlife from hurting themselves on these things, maybe there is no answer or maybe there is. Wind turbines are becoming increasingly efficient, producing great amounts of electricity. Today's massive 40- to 50-story turbines convert kinetic energy in the wind into mechanical energy, while leaving plenty of room on the ground for farming or other activities.
