Energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed.
Types of Energy Sector Companies
Below are some of the types of companies found in the energy industry. Each has a distinct role to play in bringing energy to businesses and consumers.
Oil and Gas Drilling and Production
These are the companies that drill, pump, and produce oil and natural gas. Production typically involves pulling oil out of the ground.
Pipeline and Refining
Oil and natural gas must be delivered from the production site to a refinery to be refined into a final product such as gasoline. Companies within this portion of the energy sector are called mid-stream providers.
Electricity and Natural Gas Utilities
These are utilities that provide energy and electricity to companies and homes. Duke Energy, for example, owns multiple utilities.
Mining Companies
Coal companies could be classified as energy companies since coal is used to power plants, including nuclear.
Renewable Energy
Clean energy has gained traction and investment dollars over the years and is likely to be a growing part of the energy sector in the future. Examples of renewable energy include wind and solar.
Chemicals
Some companies specialize in refining oil and gas into specialty chemicals, although many larger oil producers such as Exxon Mobil are integrated energy producers, meaning they produce multiple types of energy and control the entire process.
Examples of Energy Sector Investments
Investors have numerous choices for investment opportunities in the energy industry, including equities of energy companies, mutual funds, exchange-traded funds (ETFs) as well as the ability to buy the commodities.
Exchange-traded funds (ETFs) are a basket of investments, such as stocks, that track an underlying index. Mutual funds, on the other hand, are a portfolio of stocks or investments that are selected and managed by a portfolio manager.
The total energy of a system can be subdivided and classified into potential energy, kinetic energy, or combinations of the two in various ways. Kinetic energy is determined by the movement of an object – or the composite motion of the components of an object and potential energy reflects the potential of an object to have motion, and generally is a function of the position of an object within a field or may be stored in the field itself.
some form of energy are Mechanical, Electric, Magnetic, Gravitational, Chemical, Ionization, Nuclear, Elastic etc Electrical energy is a type of kinetic energy caused by moving electric charges. Electrical energy is caused by moving electric charges called electrons. Electricity is a type of energy that comes from electrical energy. Kinetic energy is the energy of a moving object. The amount of energy depends on the speed of the charges – the faster they move, the more electrical energy they carry.
Electrical energy is generated in the same way regardless of the starting form of energy. For example:
In a nuclear power plant, nuclear energy heats water into steam The steam is used to turn a turbine blade, which fires up a generator to give electric charges their energy.
In a hydroelectric plant, falling water is used to spin the turbine blades. The blades turn the generator to create electrical energy.
In a windmill, wind power turns the turbine blade, makes the generator create electrical energy.
Solar energy is energy produced directly from the sun. Solar energy can be converted into electricity, or used to heat air, water or other fluids.
Some more examples of electrical energy In a car battery, a chemical reaction creates an electron which has the energy to move in an electric current. These moving charges provide electrical energy to the circuits in the car. During a thunderstorm, lightning is an example of electrical energy – what we can see is electricity in the atmosphere being discharged. Electric eels generate electrical energy, which they use to defend against predators and to stun their prey.
