Energy Resources

Nonrenewable Energy

Nonrenewable energy is a source of energy that exists in limited quantities and, once used, cannot be replaced except over millions of years.

Examples:

• Coal (fossil fuel)
• Oil (fossil fuel)

Renewable Energy

Renewable energy is a source of energy that can be replaced in a relatively short period of time.

Examples:

• Hydroelectric

• Geothermal
• Wind
• Biomass
• Nuclear fusion (potentially in the future)

Most renewable energy originates from the sun.

Fossil Fuels

Oil, natural gas, and coal are known as fossil fuels because they were formed underground from the remains of once-living organisms. Fossil fuels are relatively inexpensive and are usually readily available, but their use creates... Continue reading "Renewable & Non-Renewable Energy Resources: A Comprehensive Guide" »

The Revolutions of 1905 and 1917

In 1905, general discontent combined with the fact that Russia had been defeated by Japan in the Russo-Japanese war set off a revolution that forced the Tsar to create a parliament, or Duma, and implement certain reforms. However, the autocracy remained.
