Strategies to Increase Energy Supply

What are the strategies used to increase energy?

How do they produce energy? How can they increase energy supplies? What are their pros and cons?

Renewable Energy Website

The Solutions Project

A. Renewable Energy Sources:

1. Biomass


2. Wind

3. Hydro

4. Tidal

5. Geothermal

6. Wave

7. Solar

B. Non-Renewable Energy Sources:

1. Fossil Fuels
Conventional and unconventional

2. Nuclear


What are the advantages and disadvantages of Natural Gas?

Cleanest of the fossil fuels with 45% less CO2 emissions than other non-renewable sources and less toxic chemicals like NO and SO2

Some gas reserves are in countries that are politically unstable or prepared to use gas supply as a political weapon.
Contributes to global warming by producing CO2 and methane emissions.
Relatively abundant compared to other fuels. This is increasing as technology makes exploitation of shale gas more economic.
Dangerous if handled or transported carelessly.
Less risk of environmental accidents than oil
Can be transported in a variety of ways ie through pipelines or by tankers over land or sea.
Fracking is controversial. Lots of water is needed. Wastewater and chemicals could contaminate groundwater and minor earthquakes are possible.

Pipelines are expensive to build and maintain.
Produces competitively priced electricity.
Is odourless and leaks cannot be detected unless odorant has been added to the gas.

Does not produce waste such as coal ash.
The extraction infrastructure is less harmful to the landscape.
It is lighter than air and so disperses quickly if leaked.
An economic and instant fuel for heating water and large areas, as well as, for cooking.

It allows precise control and quick results when used.
