Geothermal energy is often viewed as a relatively new form of alternative energy. In truth, the use of geothermal energy stretches far back into the past.

Looking To The Past Of Geothermal Energy

Geothermal energy is literally, “earth heat”. This type of energy’s name comes from two Greek words: “geo” meaning earth, and “therme”, which means heat. While it may seem that the use of geothermal energy is a relatively new idea, it is actually an ancient practice. Many different cultures have used geothermal power to their advantage, dating back to some of the Earth’s earliest civilizations.

In order to use geothermal energy, the energy source itself must be tapped into. Geothermal energy comes from reserves of water located in the Earth’s layer of magma. Magma, otherwise known as molten rock, is a super hot substance that springs directly from the Earth’s core, which is a scalding 9,000 degrees Fahrenheit. Magma heats the reserves of water located in its midst to very high temperatures, around 700 degrees Fahrenheit. These geothermal reservoirs, as they are known, can be drilled into or can escape naturally through cracks in the Earth’s crust. These natural formations create such places on Earth as hot springs and geysers.

With renewable energy all the rage these days and fossil fuel costs soaring, solar energy is in the news. Here are some thoughts about solar as a viable energy platform.

Overview of Solar As An Energy Platform

Energy is an important topic that is on many peoples minds these days. With the rising costs of fuel and electric power, many households and individuals are considering alternative power sources. Solar is one of the more cost effective and biologically sound alternatives available.

One of the most interesting aspects of solar energy is how little of the energy production on the planet comes from the harnessing of the energy of the sun. In fact, only 0.1 percent of the power used today comes from converting sunlight into electrical current. It would be possible, however, to obtain enough power to run all of the worlds energy needs using solar energy. If more people were willing and able to install solar collectors on their homes and even their cars when technology gets to that point, solar energy could more than cover the Earth’s power needs for transportation and housing.

As we look to alternative energy sources for our power hungry world, geothermal energy is getting attention. Here is a brief overview of geothermal energy.

Overview of Geothermal Energy

There are many different types of energy available to power our world. For years, people have used the power of burning fossil fuels, such as coal (also used to produce steam power) to create energy. In recent times, there has been a shift to using renewable resources to create the energy we need. These resources include hydroelectric power, solar power, wind power, biomass energy and geothermal energy. While many people know about the first four of these resources, geothermal energy is less well-known.

The word geothermal comes from two Greek words, “geo” and “therme”. These words mean “earth” and “heat”, which pretty much describes what geothermal energy is. Geothermal energy is energy that comes from the heat of the Earth, deep underground. The Earth’s core, where chemical reactions create massive amounts of heat, is 4,000 miles below the Earth’s surface. In this core, temperatures can reach up to 9,000 degrees Fahrenheit, and this extreme heat can be used to produce energy.

Earth the great giver. What can we learn from the Earth? The world celebrates earth day in different ways. In the United States of America, it is observed on the 22nd April, while the international earth day is celebrated on the day of Vernal Equinox .

The day is observed to make all of us aware of our responsibilities towards our mother earth. The way we have been taking all that we can from the earth will one day finish all the coal and hydrocarbon from the earth. Same with all the minerals. We are extracting what all we can. The earth is our greatest friend but we earthlings behave as if we are the masters. The earth supports us in all the ways. It gives us the atmosphere to breathe, the water to drink, and food to eat. It gives us thousands of varieties of plants and it gives us the place to make our home. The earth gives its all to us without any protest.
