Alternative energy solutions are a topic of intense interest worldwide. Research and development into new methods to generate and harness power continues although some tend to forget that there are already some pretty viable solutions readily available. Just look at the New Zealand territory of Tokelau if you need an example.

This group of three small islands in the South Pacific now have enough solar panel installations to completely meet their electrical energy needs. Up to this point, the islands had to rely on imported diesel fuel to power electrical generators. As New Zealand Foreign Affairs Minister Murry McCully points out, this had heavy economic and environmental costs.

The $7 million project was funded by the New Zealand government. A collection of solar panels were installed on each of the three islands. The last of the panels were put into place earlier this week, according to the BBC.

Keep in mind of course that these are three very small islands. Collectively, the islands consist of just 12 square kilometers of land mass and have a population of only 1,500. That said, it’s a pretty big deal for the territory as project co-planner Mike Basset-Smith said the government would now be able to invest more money into social welfare projects – money that used to be spent on diesel fuel.

The territory lies in the Pacific Ocean between New Zealand and Hawaii. Some of its nearby neighbors include the islands of Samoa and Fiji.
