Natural GasPRESENTED BY SARAH SHAQUOYA & NICK

Questions to Consider

Where are the nonrenewable sources of energy located?

How easy is it to gain access to these sources?

What are the consequences of using these sources (fuels)?

What are the costs (direct and indirect) of using these sources?

Are there viable alternative sources of fuel?

What is the current cost of crude oil and other forms of energy?

What else have you learned about these resources?

What is the political environment for these energy sources?

Natural Gas

Fossil fuel

Gas with mixtures of methane, carbon and other chemicals

Energy source

Beneath the earth

Usage

Power generation

Fertilizer

260,000 homes across the North Island for cooking, space and central heating.

Commercial Applications: hotels, motels, restaurants, office buildings

Sources& Methods

Drilling

Coal beds

Shale

Power plants

Fracturing

Cost

Natural gas still has relatively low capital costs and favorable heat rates for new power generation plants over oil and coal.

The extraction of oil and coal is too expensive compared to the many different ways that natural gas can be produced.

Cost of natural gas is slowly increasing as consumption is also increasing each year

Future Outlook

World energy consumption is estimated to grow by 56 percent from 2010 to 2040.

Global natural gas consumption increases by 1.7 percent per year.

By 2040, the natural gas consumption is expected to grow by nearly 64% globally.

Emergence of more developing countries

Natural gas is estimated to grow in production due to:

Technological innovations

New reserve discoveries

Storage & Transport

Low density: not easy to store or transport by vehicle

Underground

Advantages

Burns clean compared to cola, oil (less polluting)

70% less carbon dioxide compared to other fossil fuels

helps improve quality of air and water (not a pollutant)

does not produce ashes after energy release

has high heating value of 24,000 Btu per pound

inexpensive compared to coal

no odor until added

Disadvantages

Not a renewable source

Finite resource trapped in the earth (some experts disagree)

Inability to recover all in-place gas from a producible deposit because of

Unfavorable economics and lack of technology

It costs more to recover the remaining natural gas because of flow, access

Combustible

Toxic

Saftey

Never keep flammable liquid or any combustible material near your furnace or water heater

Maintain pipes

Install earthquake valves on your house piping that will automatically shut off gas in the event of an earthquake
