Report – EV1001 – Alternative Energy Sources

Alternative Energy Sources.

We have a problem, not an everyday problem but a huge environmental problem.

We have a lot of people on this earth who live like we think is normal i.e. with a lot electronics around us.

We are surrounded by it, let us look at a normal day for a “normal” person:

We are woken up by an electronic watch, and we turn the electronic lights on.

We jump into the shower, and turn the warm water on ( heated by an electronic device ) and then we pick out the breakfast out of our electronic fridge, and then we go back to the bathroom and uses more heated water to shave, brush our teeth a s o.

When we are finished we come to school and we noticed that we had some time over so we go into the computer facilities to cheek our electronic mail, on a electronic computer, in a electronic chilled room ( aircon ), and to light the place up we use electronic light again..

Then we noticed it time go to the lecture in another electronic chilled environment, were we use overheads, visualalizer, video, a s o…

I can go on and on, but I think you got the point I try to make, that it all around us.

Australia uses coal power plants, while US, and an majority of Europe uses Nuclear power.

I have that view that Nuclear power is the cleanest and most environmental power source we have to day.

But have said that, I dont mean that we not should research for other energy sources, such as fusion power-plants. Though nuclear power is not an future solution, due to the waste products of radioactive compounds. And obviously should everybody who has a possibility to use i.e. solar radiation to heat the households warm water supply, do that, not only to save money for them self, but to save energy.

For an example; in our household (caring 6 persons ) we had two meters and I assume that the meter that had the least difference between the readings, was the warm water meter. And if our landlord would have used solar heated water we would cut our energy with 65 kWh per week !!! ( around 11 kWh / person )

Maybe doesn’t sound that much but if you add them all up, we would decrease Townsville and Thuringova’s energy need with 1.53E6 kWh / Week. ( calculated on Townsville City Council’s estimated population and my households warm water use. )

As it said in the Prac. Manual on page 5 that 12% of the generated energy is used in people homes, and mostly during peak times. The reason for that, I reckon is that many of us work within the same timetable meaning that we go up about the same time in the mornings, we start work at the same time, we come home and cook dinner at the same time and most of us end up in front of the TV at the same time.

It is very hard to change that, so we have to make the changes some were else.

This could be using wind energy, and solar panels. An area like Townsville has an natural surplus of solar energy, so it is very weird that you Aussies dont use it more than you do.

Back home in Sweden, we uses, heaps of different energy sources, to mention some; hydroelectric, wind, nuclear power and something new that came for 10 years ago, something called biogas, whish was the farmers who had material e.g. horse, cow and pig feces, that they transported to an close by facility that extracted methane gas, whish was then returned as heat to the close by suburb.

Conclusion:

The alternative energy sources you can use varies from what corner of the planet you are in.

I.e. In the Northern parts of Europe -Scandinavia – you have to use something that you can produce a lot of energy out of in a cheep and environmental way, e.g. animal feces, river streams and wind power plants.

Though we dont got so much sunlight.

In the Southern hemisphere, like here in Townsville, you have to use the strong sun, whish you have a lot of, and the heat you have all year around, to heat water up and extract energy through solar panels.
