Advantages: Lasts forever
Disadvantages: Expensive as hell, payback times are pianfully long
Renewable energy, wether we like it or not, is what we will have to rely on.
Wind power at the moment is not profitable, it costs too much to build and maintain wind turbines, and they do not pay back enough. Tidal power is good, if you can get permission to build a damn in some of the biggest river mouths of your country. Geothermal and hydroelectric power are the best alternative energy sources.
Geothermal is taking the earth's heat to generate energy, the trouble with it is that the earth's heat is only accessible in some areas, mainly ones with volcanic activity.
Hydroelectric is a reliable method of power generation, but again, is only viable in certain areas. Mainly mountainous or valley regions. Hydroelectric power is also hugely expensive to construct.
There are countries in the world running on nearly all renewable energy. Nuclear is a good alternative while we build renewable technology, but eventually, we will need it.
Summary: A neccessity, and not one we like

- 16/11/09 is the title the wrong way round? i.e: Renewable's great for now, but nuclear will be needed eventually. |

- 07/11/09 @helencb, i cant remember which country it is, one of the northern European ones.
Its population is tiny compared to its land mass, they made a huge amount of money from selling their oil and invested in hydroelectric dams because the nation is mountainous.
T hey are around 98% or 99% reliant on renewable energy.
My conclusion was that hydroelectric and geothermal are the best of the renewables, but how is a country on deep crust meant to work off geothermal, and a non-mountainous nation meant to run off hydroelectric.
Nuclear is the only option for some countries, while others can live on renewables. |

- 06/11/09 this is not particularly in depth and I am not sure how accurate you are...especially about countries running all on renewables (other than extremely poor nations). Hydro can be small scale and most hydro stations have been in place for years, and are not that expensive to run either. Wind is competitive. Your conclusion that hydro is the best doesnt seem to fit your own conclusions later... |
