Major energy providers are as per below:
Old energy : Oil, hydroelectricity, coal and nuclear
New energy: Solar, wind, wave and hydro
It is also learned that old energies are not only harmful to environment, but were also making big problems in the making process. Let's line-up some of its..
Events/tragedy occurred during old energy making:
1. Chernobyl nuclear plant meltdown (1986) - 4,000 cancer dead
2. Gulf war oil spill (1990) - damage on environment
3. BP Gulf of Mexico oil spill (2010)
4. Others are long-term damage due to the carbon released to the air resulting global warming
Since there are many long-term negative impacts for us, let us learn about the new energy (good, clean, renewable and non-hazardous). Major energy providers are per below:
Solar:
Photo-voltaic panel/cell is still expensive in the market, but the part cost is expected to drop gradually. the big challenge is how to adopt large-scale cells for big area usage.
Wind &Wave:
High investment is required, especially for wave energy.
Trash:
This is interesting one for me because I like to do gardening. Gardening and 'making energy from trash' have some similarity. Someone must appreciate the nature in order to apply this source of energy. Denmark is one of the leading country in processing toxic, trash, raw materials and others into heat & energy which to be used by homes later on.
