Energy Is the ability to do work. In the last handout, heat was listed as a form of energy There are different forms of energy: 1)Chemical – stored energy such as in coals and in batteries 2)Electrical 3)Nuclear – the energy that exists within the nucleus of an atom 4)Mechanical – energy an object has when in motion 5)Sound 6)Heat

DESCRIPTION

Is it possible? To use one type of energy to get another type? The answer is yes… we use chemical energy (fuel) to make electricity and then this is converted to light energy or even sound energy.

• Energy can be classified as mechanical or non-mechanical

• Mechanical energy includes kinetic energy (the energy of a moving body)

and potential energy (stored energy). Potential energy may be classified as chemical, gravitational, or elastic

• Non-mechanical energy includes light, heat, sound, electrical, and nuclear

Energy can be changed from one form to another.

At times we have a form of energy but it is not the one convenient for use. Therefore, we must convert it to another form.

But energy can neither be created nor destroyed but can be converted from one form to another

Solar

- light can be converted to electrical energy using solar panels and photovoltaic cells

- heat can be used for solar water heaters, solar stills, solar crop driers

Issues

• Costly panels• Amount of light/heat received variance

Wind

- Clean- Indigenous- Renewable -NE trade winds are the primary

regional wind systems in Caribbean, greatest in Northern Caribbean and lowest in western Caribbean and Bahamas, 9am to 4pm

Wind

- windmills used in Caribbean islands for electricity grids: Cuba, Curacao, Guadeloupe and Jamaica (Montseratt put out of commission because of volcanic activity

Installed but non-operational in Antigua, Barbados, Trinidad and Tobago

- Can be used for water pumping in Aruba, Bonaire, Cuba, Curacao, Dominican Republic, Guyana and Jamaica

Wind – out of the Caribbean

• Argentina• Brazil• Costa Rica (region’s largest plants)• Peru• Mexico

Environmental issues

• Acoustic noise emission (but with new technology blades are less noisy)

• Visual impact• Electromagnetic interference influencing

the reception of radar, radio and television signals

• Hydro electric power plants are popular in places like Canada, Venezuela (leading Latin America) and Dominican Republic.

• Hydropower plants are actually based on a rather simple concept -- water flowing through a dam turns a turbine, which turns a generator

• … there are above ground plants and underground plants (such as in China)

Hydro-power

ActivityCan Trinidad and Tobago use alternative energy

sources to provide power?• In groups quickly answer the following questions 1) What are some options available?2) Using the information provided, decide on one

alternative source that may be suitable for Trinidad or Tobago.

3) What may some disadvantages of your choice?4) Evaluate the impact this will have on the

environment and the inhabitants.
