Planet earth is warming faster than at any time in the past one

thousand years and there is little doubt that human activity is to

blame.

There are many things we could do to stop the effects of global

warming. One is to start recycling this would help clean up the earth.

And people could stop smoking and they could not use their cars as

much. Instead of fuel we could use solar power or any renewable

source.

There is increasing interest from governments in renewable energy

supplies as a means of reducing greenhouse gases and global warming.

The oceans are widely recognized as having the potential to provide a

significant percentage of our energy requirements, and ongoing

research is mapping this resource in detail. Current designs require

extraction devices to be comparable in size to the length of a

"typical wave". There is evidence to suggest that much smaller point

absorbers could extract energy more efficiently than current designs.

There are also opportunities for both natural and man-made

concentration of waves in gullies and inlets.

Governments are increasingly looking towards wind power and other

renewable energy sources to combat increasing greenhouse gases and

global warming. During its operating life, a typical wind turbine can

produce 80 times the energy used to build, operate, and dismantle it.

Public opinion is broadly in favour of wind power, but the

environmental impact of wind farms could be a barrier to future

developments.

Table 7: New Sources of Renewable Energy

Despite the small potential contributions of new renewable sources to

the total energy demand in the next 20 years, as indicated in Table 6,

longer term projections may be more appropriate to show the impact of

the full assimilation and use of renewable resources. The projections

over the next 100 years given above suggest the substantial

contribution that renewable can potentially achieve.
