Thermal energy defined

The most common definition of thermal energy is this: it is a part of the entire total internal energy of a sample of matter or a thermodynamic system which includes various forms such as the chemical energy and nuclear energy which are considered forms of potential energy. Thermal energy is created and measured by any kind of heat. Heat is caused by the increase in the velocity or activity of the substance’s molecules. These activities cause the temperatures to rise.

How does thermal energy work?

Thermal energy is the kinetic energy of the atoms, molecules or particles in plasma that originates from disordered motion of the particles in a bigger ensemble. The energy is equally divided among the quadratic degrees of freedom of the particles.

It is important to take note that thermal energy is different from heat. In physics, heat is only a characteristic of the process of energy exchange. In addition, matter does not contain heat—it contains thermal energy that can be transferred or converted within a system. In the laws of thermodynamics, energy in the form of heat can be transferred from one concrete object to another. For example, when you place a pot of water over fire, the water will slowly become warm until it reaches the boiling point that makes the molecules move very fast.

How did humans use thermal energy?

By having a good understanding of the principles of thermodynamics, humans have been able to harness the natural sources of heat to generate thermal energy. The sun, volcanoes, geysers and ocean can be considered as sources of thermal energy. In fact, humans are trying different ways to switch to sustainable and renewable sources of energy to decrease dependence on non-renewable sources. As the fossil fuel resources become rapidly depleted, there is no other way to save the planet but to use alternative power sources such as the thermal energy to provide power to the various activities of humans. There are several natural sources of thermal energy on this planet, we just need to harness them the proper way.

Advantages:

• Wind power is very abundant and can be availed completely for free.
• Using wind turbines does not generate radioactive wastes and pollution. Its construction also has less impact on the environment.
• It can be used to provide electricity to homes and facilities which are self-reliant. This does not need fuels and other materials. Also, when natural disasters happen, the people with windmills on their homes will not lose their electricity.
• Wind power can create enough energy for a huge number of people with the use of bigger turbines which are connected to electrical grids. People can still gain the advantage without owning or maintaining the pieces of equipment.
• Wind power is considered as a “permanent energy” which would still exist even if the sun has finally reached its end.
• The cost of wind power turbines for residential purposes has significantly decreased while its efficiency has dramatically increased.
• Wind energy is considered as a great supplement to other sources of renewable energy such as the hydro and solar power.
• Power generation using the wind does not use any non-renewable resources such as natural gas, oil and coal.
• This type of energy is readily available in any parts of the world.

Disadvantages:

• Since some people consider the turbines to have an unpleasant appearance, they do not opt to use wind power.
• Wind turbines can be damaged by storms because of their thinness and height. Most damages on wind turbines are caused by lightning according to the National Lightning Safety Institute.
• The blades of the turbines can hit other biodiversity creatures such as insects and birds.
• There are some wind turbines that generate loud noises. These are common especially when the speed of the wind is slow.

Wind power is very promising because of its advantages. It also provides people with a self-reliant and inexpensive way to generate electricity. On top of that, wind turbines require minimal maintenance.

If they are successful with their green technology endeavors, it would be possible that in the near future we would be able to use these alternative energy sources to their full potential.

There are three remarkable countries that are channeling full attention to the renewable energy sources.

Canada

This developed country is giving emphasis on energy conservation and efficiency to meet several objectives. Majority of the financial incentives are channeled to water heating and solar space in industrial developments although financial assistance is also available for solar hot water systems at homes. Property owners of existing homes can avail of federal grants by leveling up the energy efficiency of their houses and reducing their environmental impact. On the other hand, new homes must match the R-2000 standard set by the government for higher energy efficiency.

United Kingdom

In the early part of 2007, the existing grant scheme was ended and a revision of the Low Carbon Buildings grant program was introduced for householders. Before a homeowner can apply for the grant, the homeowner must undergo through several energy efficiency evaluation to make sure that he or she is minimizing the energy requirements. The maximum grant is £2,500 (solar photovoltaic system) and £400 (solar thermal hot water system). Other technologies may be installed by the owner in the same property but the maximum grant is fixed at £2,500.

United States of America

This country has a combination of state, federal, local and utility grants and incentives for the solar power systems for homes. The incentives are available for different home energy efficiency savings as well.

• State and local - Several schemes are offered, and homeowners are recommended to go to the Database of State Incentives for Renewables and Efficiency (DSIRE) to gain access on the these incentives.
• Federal – In 2008, the Federal government provided a tax credit of up to two thousand dollars for installing solar power systems. This covered the use of photovoltaics, fuel cells, solar water heating and other solar technologies.

With the growing popularity of the use of solar energy as an alternative energy source, more and more homeowners are engaging in do-it-yourself solar energy projects. To ensure that your DIY solar powered project will be a success, it is important to note the following:

• Only take on solar powered projects that make sense to you. If you only have basic DIY skills, then you should stick with simple DIY solar powered projects. In case, you want to take on more complex projects, it would be a good idea to ask assistance from someone who is familiar with the project you wish to do.
• Assess your DIY skills before taking on any kind of DIY solar powered project. Just because your friend was able to successfully finish a particular DIY project does not instantly mean you can to. That said, you have to always take note of your DIY skill level first before taking on any DIY solar powered project.
