ACTIVITY

COLOMBIA:

* Hydro electric Power:
Advantages:
* Provide more than 70% of Colombia’s electricity
* Colombia have facilities to create a hydroelectric station, because we have a lot of rivers
Disadvantages:
* The social cost and the ambiental problems that a hydroelectric station wouldgenerate, means a problem to the government and Colombian’s.
* The climatic changes like the precipitation and the “Fenómeno del niño”, shows dry periods that could affect the hydroelectric stations.
* Solar Power:
Advantages:
* Solar systems can be very suitable for applications in rural areas, where energy demands are dispersed and modest and grid connections is often more costly.Disadvantages:
* Colombia has significant solar power resources because of its location in the equatorial zone, but the country sits in a complex region of the Andes where climatic conditions vary.

* Wind Power:
Advantages:
* The wind regime in Colombia is among the best in South America. Off shore regions of the northern part of Colombia , such as in the Guajira Department, havebeen classified with class 7 winds (over 10 meters per second).
* Colombia has an estimated theoretical wind power potential of 21 GW just in the Guajira Department- enough to generate sufficient power to meet the national demand almost twice over.
Disadvantages:
* However, the country only has an installed capacity of 19.5 MW of wind energy, tapping only 0.4% of its theoretical windpotential.
* The turbines are too noisy to be implemented on urban areas.

* Tydal Power:
Advantages:
* The tidal energy doesn’t depends about the climate, because the rise and fall of the tide is consistent, which makes it very predictable and reliable, so there’s not any problem if we’re have the raining season or the sunny season, the energy will never stops.
* Colombia hasthe possibilities of use the two oceans to produce the energy so we can obtain more energy of a natural source.
Disadvantages:
* The pollution and ecosystem problems that will be generated during its building are going to be incredible high.
* They’re a few places that are right to put on this tidal power installation.
* They need a long period to be developed and Colombians don’thave such patience.

ZIMBABWE

* Hydro electric Power:
Advantages:
* Their Hydro-electric power station that is called The Kariba Dam supplies 1,266 MW of electricity to parts of Zambia and Zimbabwe and generates 6,400 GW per annum, this supply for electricity a big part of those two countries.
Disadvantages:
* The environmental impacts are incredible big, several thousandlarge animals threatened by the rising water were rescued by Operation Noah.
* The creation of the reservoir forced resettlements to about 57,000 Tonga people living along the Zambezi in both Zambia and Zimbabwe.

* Solar Power:
Advantages:
* In Zimbabwe it improves the sustainability of livelihoods among the rural poor, answers the call for frequent power cuts in urban areas andcould be a long-term solution for energy requirements within the small scale-farming sector.
* There is a great potential for developing solar in Zimbabwe.
* The market is very vast, ranging from angry urban dwellers who have endured regular power cuts for several years, and the rural folk eager to see the light; the country has an abundance of sunlight, which is being under-utilized.Disadvantages:
* Zimbabwe’s government won’t introduce on many solar panels considering it is a poor country and the solar power is very expensive to introduce. For them it is better to invest on other projects of social issues than in new forms of energy.
* Wind Power:
Advantages:
* A wind turbine installed in a village in Zimbabwe may help decrease vulnerability, for improving...
