Why We Need Alternative Energy Sources!!!

As the July comes to a close so does our discussion on energy...

There is a need for alternative energy sources, hence the development of renewable energy is moving fast. Nationally and internationally various individuals and research companies are creating new and exciting forms of energy. Why do we need to make greater use of these energy sources?

The first problem is that the fossil fuels are depleting in a rapid rate and are harder to retrieve. The consequence is that we can be facing an energy crisis in the future is we are not careful today. The energy prices will sky rocket and not be available for many individuals or countries. The second problem is that the fossil fuels that are widely used today are harmful for the environment.

The solution for the above problems can be resolved by renewable energy. Our beautiful planet gives us the opportunity to make proper us of sunlight, flowing water, strong winds, and hot springs and convert these into energy. These energy sources are abundant and free to use. We must be sure that we convert the energy the right way, without causing other problems that can again hurt our environment. Luckily the many efforts by individuals and companies show that this can be done.

Renewable Energy!!!

There are many different types of energy and many ways to save energy. Renewable energy sources can be replenished in a short period of time. The five renewable sources used most often are:

biomass - including wood and wood waste, municipal solid waste, landfill and biogas, ethanol, and biodiesel
water (hydropower)

The use of renewable energy is not new. More than 150 years ago, wood, which is one form of biomass, supplied up to 90 percent of our energy needs. As the use of coal, petroleum, and natural gas expanded, the United States became less reliant on wood as an energy source. Today, we are looking again at renewable resources to find new ways to use them to help meet our energy needs.

Uncertainty about the future of fusion research has increased the importance of "renewable" energy sources. Among the most important of these sources are hydroelectric, solar, and wind. As you will see, renewable energy sources' main assets are their environmental cleanliness and their virtual inexhaustability. Major drawbacks, however, are limited energy production (in most cases not suitable for large-scale power generation) as well as relative costliness to build and maintain. In light of diminishing fossil fuels, however, renewable energy may end up as the energy of choice for the 21st century.

Most geothermal reservoirs are deep underground with no visible clues showing above ground.

Geothermal energy can sometimes find its way to the surface in the form of:

      • volcanoes and fumaroles (holes where volcanic gases are released)

      • hot springs and

      • geysers.

The most active geothermal resources are usually found along major plate boundaries where earthquakes and volcanoes are concentrated. Most of the geothermal activity in the world occurs in an area called the Ring of Fire. This area rims the Pacific Ocean.

When magma comes close to the surface it heats ground water found trapped in porous rock or water running along fractured rock surfaces and faults. Such hydrothermal resources have two common ingredients: water (hydro) and heat (thermal). Naturally occurring large areas of hydrothermal resources are called geothermal reservoirs. Geologists use different methods to look for geothermal reservoirs. Drilling a well and testing the temperature deep underground is the only way to be sure a geothermal reservoir really exists.

Most of the geothermal reservoirs in the United States are located in the western states, Alaska, and Hawaii. California is the state that generates the most electricity from geothermal energy. The Geysers dry steam reservoir in northern California is the largest known dry steam field in the world. The field has been producing electricity since 1960.

The word geothermal comes from the Greek words geo (earth) and therme (heat). Geothermal energy is heat from within the earth, we can use the steam and hot water produced inside the earth to heat buildings or generate electricity. Geothermal energy is a renewable energy source because the water is replenished by rainfall and the heat is continuously produced inside the earth.


Some applications of geothermal energy use the earth's temperatures near the surface, while others require drilling miles into the earth. The three main uses of geothermal energy are:

1) Direct Use and District Heating Systems which use hot water from springs or reservoirs near the surface.

2) Electricity generation in a power plant requires water or steam at very high temperature (300 to 700 degrees Fahrenheit). Geothermal power plants are generally built where geothermal reservoirs are located within a mile or two of the surface.

3) Geothermal heat pumps use stable ground or water temperatures near the earth's surface to control building temperatures above ground.

Types of Energy!!!

Mechanical, Electromagnetic, Electrical,
Chemical and Thermal

What is Mechanical Energy?

o Energy due to an object’s motion (kinetic) or position (potential).

o The bowling ball has mechanical energy. When the ball strikes the pins, mechanical energy is transferred to the pins!

What is Electromagnetic Energy?

• Light energy
o Includes energy from gamma rays, xrays, ultraviolet rays, visible light, infrared rays, microwave and radio bands

What is Electrical Energy?

• Energy caused by the movement of electrons
o Easily transported through power lines and converted into other forms of energy.

What is Chemical Energy?

• Energy that is available for release from chemical reactions.
o The chemical bonds in a matchstick store energy that is transformed into thermal energy when the match is struck.

What is Thermal Energy?
• Heat energy
o The heat energy of an object determines how active its atoms are.

o A hot object is one whose atoms and molecules are excited and show rapid movement.
o A cooler object's molecules and atoms will show less movement.

Understanding the water cycle is important to understanding hydropower. In the water cycle - According to the Energy Information Association (2008)

Solar energy heats water on the surface, causing it to evaporate.

This water vapor condenses into clouds and falls back onto the surface as precipitation.

The water flows through rivers back into the oceans, where it can evaporate and begin the cycle over again.

Mechanical energy is derived by directing, harnessing, or channeling moving water. The amount of available energy in moving water is determined by its flow or fall.Swiftly flowing water in a big river, like the Columbia River along the border between Oregon and Washington, carries a great deal of energy in its flow. So, too,with water descending rapidly from a very high point, like Niagara Falls in New York. In either instance, the water flows through a pipe, or penstock,then pushes against and turns blades in a turbine to spin a generator to produce electricity. In a run-of-the-river system, the force of the current applies the needed pressure, while in a storage system, water is accumulated in reservoirs created by dams, then released when the demand for electricity is high. Meanwhile, the reservoirs or lakes are used for boating and fishing, and often the rivers beyond the dams provide opportunities for whitewater rafting and kayaking. Hoover Dam, a hydroelectric facility completed in 1936 on the Colorado River between Arizona and Nevada, created Lake Mead, a 110-mile-long national recreational area that offers water sports and fishing in a desert setting.

Hydropower is the largest source of renewable energy. This renewable source of energy provides 10% of the nation’s electricity. As of now, there are 77,000 Megawatts of hydropower, enough to provide 35 million homes with energy. Converting flowing water into usable energy produces hydropower. Most of this water comes from rivers and is released through turbines to produce energy. Although this power source does not release pollution, it can possibly harm fish and wildlife, displace people, and alter the quality of water.

There is a really great HydroPower Kit for kids by Thames & Kosmos; you can find it at

Wind Energy!!!

Wind energy produces about 2,500 Megawatts of energy, and generates a mere .1% of our electricity. The wind rotates blades around a hub, which is connected to the main shaft. The main shaft spins a generator. The size of turbines is determined by how much energy is needed. Small wind turbines are usually used for homes, farms and ranches. Other ways to use wind energy include grinding grain and pumping water.

Wind is classed in categories of 1 through 7, with 7 being the highest and 1 being the lowest. A good wind source that has a class of 3 or higher is the east coast and along the Appalachian Mountains. North Dakota is an excellent wind source.

The Green Effect!!!

We had entered a contest from National Georgraphic and Sun Chips, we had hoped to let our supporters know our idea had been chosen. Even though our idea did not fall in the top 1o it does not mean we have to forget about it. Our idea will work in so many communities and we challenge you to carry our idea forwards, we are not giving up!!! We are posting our idea below, we also ask that you visit the National Geographic Site and review the winning ideas and vote for your favorite.

Earth-Kidz -Easy Recycling Idea:

Our idea is to bring recycling a step further and make it as simple as possible. There are so many items they do get recycled propery. Many people do not realize there are different ways to recycle. Batteries, light bulbs, electronics, and paint cans are just a few. Our idea is to have a facility for our town members, businesses, families, schools, etc to be able to bring these items to. A list of items and pick up dates will be distributed to the community, certain collection bins can be placed in stores and other locations, such as schools. For example we can have a battery box located next to the plastic bag recycling bin at the grocery store.

This is a small step that could be huge on many levels. The community will have an easier way to recycle more objects. Other towns will learn from our trial and error and take on the project. The impact will bring the community together and bring in new ways to recycle on a regular basis. It will help the environment by disposing of items properly, and lower a towns carbon footprint to name just a few. The prize funds would have been used to set up a location for drop off, spread the word and make the necessary drops to the proper areas. The funds would have also allowed the placement of colletions bins in specific locations for simplier drop off. Some items can only be dropped at the drop location for safety reasons, such as lightbulbs or paint. Saving the world one town at a time!

Go to and vote for your favorite idea, please remember to keep or idea alive and discuss it with your parents, schools, community leaders, churches, etc.

Thank you

Happy 4th of July!!!!!

Independence Day honors the birthday of the United States of America and the signing of the Declaration of Independence on July 4, 1776. It's a day of picnics and patriotic parades, a night of concerts and fireworks, and a reason to fly the American flag.....

God Bless the USA - Lee Greenwood - For more funny movies, click here


“Let every nation know, whether it wishes us well or ill, we shall pay any price, bear any burden, meet any hardship, support any friend, oppose any foe, to assure the survival and success of liberty." John Fitzgerald Kennedy

10 Simple Ways To Save Energy.........

1. Use energy-saving light bulbs

2. Shut off computers

3. Use “smart”power strips.

4. Turn off entertainment devices when not in use(TV, game systems,etc.)

5. Use natural light, heat and cooling.

6. Unplug your phone charger when not in us

7. Talk to your parents about ENERGY STAR appliances.

8. Talk to your parents about programmable digital thermostats.

9. Talk to your parents about Home improvements(windows, doors, roofs, etc)

What is Energy???

Energy provides us with a means of using fun and convenient appliances. But what exactly is energy and where does it come from?

Scientists define energy as "the ability to do work." For example, we harness energy to run factories, provide heat and light in our homes and schools, power our cars and school busses, and many other things!

People can take energy from different sources: fossil fuels (gas, oil, coal), nuclear power, wind power (windmills), solar power (from the sun) hydroelectric power (water dams) and a few new innovative ways. Energy is very useful to us, but energy costs us money to use in our cars, homes, work, and schools. In addition, most of the energy people use comes from fossil fuels – and this causes a lot of pollution as well as other problems.


We are going to try something a little different with our site, we are gong to focus on a different topic every month. This month we are going to focus on energy, it is a topic everyone has been hearing a lot about recently. We will be covering a variety of areas on this topic including but not limited to:

Wind Energy

Geothermal Energy



We will be exploring long term ideas as well as simple inexpensive ideas that everyone can do. It is important to remember that the little things add up to great things...
