Powerful energy resources -

People learned to break down oil into products like kerosene for lighting and cooking. Then the automobile was invented. Soon a lot of oil would be needed to make gasoline for cars. The 's A greater dependence on electricity became apparent. Electric lights, appliances and machines made life easier for Americans.

Coal, oil, natural gas and hydro water power were all used for making electricity. Then nuclear energy was discovered, and it was also used to make electricity. Americans used a lot of oil. We used it to make electricity, to make fuels for transportation and heating, and to make many products like plastic and nylon.

The price of oil went up, and so did the prices of electricity and gasoline. The supplies are finite and continue to dwindle at an accelerated rate. People began to conserve energy. They began to use the kinds of energy that Native Americans and early settlers had used, energy from the sun, the wind, and wood.

They also searched for new sources of energy, and new ways to use energy for the future. The 2,'s Predict the future in energy development in the 2,'s. They illustrate the same thing in different ways.

The story they tell is the same story you have just read. Study them carefully, and then answer the questions. Chart reprinted with permission from the New York Energy Education Handbook, New York State Dept. of Education. QUESTIONS: 1.

What were the most important kinds of energy in the early days of America? What were they used for? The American Revolution was in the 's. What was the most used fuel then? The American Civil War was in the 's.

Why did coal become so important by ? Why do you think it took so long for coal to replace wood as the most important fuel?

What was the most used fuel in What use did it have? Why do you think oil use went down and wood use went up during the 's? What sources of energy does the U. depend on most today? ACTIVITY 2: Match the pictures below with the correct titles. Some sources of energy exist in almost unlimited supply.

As soon as we use some energy, it is replaced by more. These are the round, bluish wafers that are mounted on space satellites to give them electric power from sunlight when they are in space. You can feel it in a car that sits in the sun. Houses and buildings can be designed to collect sunlight the same way.

You can also build solar collectors to trap the sun's heat. The sun heats the earth and the earth warms the air above it. Heated air rises just like a hot air balloon. This energy can be used to sail ships or drive machines to pump water or produce electricity.

The sun heats the surface water of lakes and oceans. Some of the water evaporates when it is heated. Then it forms clouds, falls as rain, and collects in lakes and rivers. The plants of the earth are solar collectors. By the process of photosynthesis, they use sunlight to produce stored chemical energy that is used for food or fuel.

Some sources of energy take so long to produce that if we use them up they can't be replaced. Dead plants and animals must decay for hundreds to millions of years to produce these fossil fuels.

Albany, NY. Quad - A gigantic energy unit often used to state how much energy entire countries buy each year. It represents a quadrillion Btu's, the amount of heat energy in million barrels of oil; a unit of energy equal to one quadrillion Btu's 1,,,,, ANSWERS TO QUESTIONS: 1. Coal and wood were the most important energy sources in the early days of America.

The most used fuel during the 's was wood. During the 's wood was still the most used fuel. Coal became important just prior to because of its many uses such as the fuel for steam engines which powered the many railroad engines popular during the period, and fuel for the steam turbines used in the production of electricity.

Coal also began to replace wood as a source of heat for commercial and residential buildings. Wood remained the most popular fuel for a long period of time because of its abundance and the fact that it was extremely inexpensive.

Oil was the most important fuel in Fuel oil derived from oil became extremely important at this time due to the mobility of the world's people and the so called "Shrinking of the globe" by faster and faster means of transportation. Oil went down due to energy conservation measures and the high price of fuel oil brought on by the Arab oil embargo.

The United States is still highly dependent on oil as its main source of energy. This is a serious problem due to its shrinking supply. What is the Best Renewable Energy Source? Electricity is produced as the waves move through the ocean; it will cause the turbines placed in the water to spin, creating electricity.

There are a few different technologies that can be used to make turbines in the ocean spin such as oscillating water columns and overtopping devices. Advantages Wave energy is a renewable energy source While generating electricity, wave energy does not produce any harmful emissions Disadvantages Wave energy structures are expensive to install in the ocean The technology cannot be used anywhere - it must be installed in regions beside an ocean with waves that would produce sufficient electricity 6.

The sunlight is captured by solar photovoltaic PV cells also known as solar panels to generate usable electricity [3]. Advantages A renewable, clean and quiet energy source Solar panels can be installed onto homes or offices, providing owners with decreased electric bills and a energy source that requires little maintenance Disadvantages The time, season, geographical region and weather all affect how much electricity solar panels generate [3] In the manufacturing process of PV cells, toxic materials are used 5.

It can be utilized to heat or cool homes, as well as produce electricity [4]. Biomass Energy Biomass energy also known as bioenergy is created from waste biomass of plants or animals. The waste from plants and animals can include vegetable oil, crops, manure or wood products [5].

A common method for creating electricity with biomass is through direct combustion. Direct combustion creates steam to cause turbines to spin, which simulates a generator to create electricity [6]. Advantages Biomass energy is a renewable energy source, as the resources that are burned grow back in a short amount of time Bioenergy decreases the amount of plant and animal waste that ends up in landfills Disadvantages Burning biomass creates emissions such as methane Growing biomass can require significant space and water 3.

Wind Energy Wind energy also known as wind power uses wind turbines to generate electricity. The sun is responsible for creating wind power, as the disparities in temperature produce wind. Often multiple wind turbines are built together, known as a wind farm [7]. There can be onshore or offshore wind farms.

Advantages Wind energy is a renewable and clean energy source Wind turbines can bring extra revenue for farmers, as they can lease out their farmland to wind energy companies [8] Disadvantages Wind turbines are expensive to build and noisy The variability in wind strength means the turbines could be producing different amounts of electricity at different times 2.

Hydroelectric Energy Hydroelectric energy also known as hydroelectric power uses the flow of water to produce electricity. Today, hydropower is generated by constructing a hydroelectric dam on a body of water. The water moves from the top of the dam through the turbines, which produces electricity.

Then, the water exits out the bottom of the dam. Advantages Hydroelectric power is a renewable energy source Hydroelectric energy is a very efficient energy source compared to others Disadvantages Hydroelectric dams are costly to built The construction of dams can harm aquatic wildlife 1.

Nuclear Energy Nuclear energy is a type of energy from the nucleus of an atom. There are two ways nuclear energy is generated: nuclear fission and nuclear fusion. Currently, only nuclear fission can safely produce electricity.

Nuclear fission is the process of separating atoms. It produces electricity by using uranium to create chain collisions resulting in the release of radiation and heat. In turn, when the heat combines with water it creates steam that turns the turbines, consequently generating electricity [9].

Optimizing Efficiency in Energy Plants with ROVs Energy efficiency is important in power plants as it allows plants to produce the maximum amount of energy possible. Remotely operated vehicles ROVs or underwater drones can help enhance the ability to produce energy efficiently in nuclear , coal, hydroelectric plants and offshore wind farms.

There are several ways ROVs help optimize energy production, these ways are through: Inspections and Maintenance Schedules Finding structural problems on power plants is essential as the issues could be harming energy production.

By using the high-quality imaging and camera rotation of the ROVs, operators can establish; where maintenance needs to be done, the type of repair necessary and the condition of the structural components.

For example, a customer-owned utility Eugene Water and Electric Board , were able to find out why the stoplogs on their hydro plant were not creating a watertight seal.

Using a ROV, the utility organization determined the cause, which was debris on the beams. Ultimately, ROVs can find minor problems before they cause massive issues to energy production. Emergency Response On a power plant, there can be times where a component unexpectedly breaks, preventing or reducing the ability of the plant to generate energy.

When this occurs, often operators will have to hire and wait for a considerate amount of time for a dive team to inspect the issue. However, with speedy deployment times, ROVs can be ready to inspect submerged infrastructure on the plant within 30 seconds. Ultimately, allowing operators to immediately find the type and location of a problem.

As a result, the user can schedule and perform repairs as soon as possible. Keep Operations Running During Inspection When performing crucial inspections, often an entire power plant must be shut down to keep the divers who are surveying safe.

While the plant is closed, there is no energy being generated. However, inspection with ROVs allows for examinations to occur, while some of the plant remains operational. As a result, some energy will be produced during inspections. Talk to us about how ROVs make structural inspections safer and easier Contact Industry Specialist.

Minimize The Use of Divers As mentioned above, divers can hinder energy production on a power plant by increasing inspection times and needing to shut down the plant. However, lessening the use of divers can have other benefits for inspections. Hiring dive teams for inspections can be expensive, as well as when plants are shut off, it can be costly.

Additionally, performing inspections can be risky for divers, especially in confined and hazardous spaces. ROVs are able to access these areas, increasing safety as divers are kept out of these dangerous scenarios. Improving Power Plant Inspections with Deep Trekker ROVs are extremely useful in improving the efficiency of power plant inspections.

These vehicles are easy to transport around an energy production facility. As well, the robots are designed to be easy to operate and maneuver in confined spaces. Ultimately, making Deep Trekker ROVs the best tool for completing thorough and effective examinations.
