Green Energy Options within the Caribbean

Bigger windmills decrease fees in line with kWh. Therefore the mainstream of the marketplace is 2-3 MW (MegaWatt = 2000-3000 kW peak potential) windmills. Their common yield is up to 1 MW, depending on wind conditions.

However, large structures additionally carry big problems with them: the complexity of installation, accessibility, upkeep. But furthermore, they require a very “strong” net (mains). Even strong nets cannot handle more than 25-30 % participation of the massive structures. The worst-case state of affairs should be considered: most wind output at the lowest strength requirement at any time. In western international, the distinction between minimal use and average use isn’t always that huge, but it reduces the wind penetration.

As the common and most yield fluctuates notably, this further reduces the wind penetration. The huge structures have (costly) alternatives to waste power into dummy loads in excessive instances. Still, nearly the most wind penetration is around 10% of the average electricity use, in Western hemispheres that is currently also visible as a realistic limit because of the limitations to region windmills on land (humans do now not just like the view). As useful as it’s far, ten percent isn’t even covering the boom of strength use.

For the huge windmills, the quality option to expand is offshore wind parks. Advanced manipulate systems will want to transfer towers on and off or, better intelligently: use storage for the excess power. When this is perfectly implemented, 25-30% of the common use can be wind power. The Netherlands is one of the nations that specialize in offshore wind parks. Recently the world’s 2nd largest offshore wind park was commissioned. The cutting-edge improvement from Norway is floating windmills tied to the lowest of the ocean.

I set up the primary windmill within the Caricom (Eastern Caribbean islands) at Paradise Bay, an inn and lodge network in Grenada. The owners of the villas and the inn revel in financial savings of up to 20%, whilst the electricity agency also saves on power cost. This is a clear case that serving the environment can be even profitable. The windmill will be commissioned later this year.

In smaller markets -together with the Caribbean- massive is not as stunning as inside the West as the nets are relatively small, and the infrastructure to install and hold the huge structures is limited. A corporation from the Netherlands (www.Mainwind.Nl) recognized this hole and supplies solutions inside the form of used mid-range windmills (250-750 kW) that come from upgraded wind parks.

The want for upgrading is plain; it’s miles maximum smooth to boom capacity to the current generation (2 – 3MW) at existing wind parks. The smaller windmills are taking down, absolutely revised (reconditioned), and offered with an as-new guarantee and optionally with a fifteen-year all-inclusive maintenance settlement. The fee in keeping with kWh is competitive with large windmills, commonly between 7-nine US$ cents; 5-6 instances lower than the mains.

While that is a completely beneficial investment, nearby bankers seem to have bloodless water worry, so there’s a possibility right here for people who need to delight each other’s environment and wallet!


Photovoltaic systems were once only appropriate for small-scale electricity requirements. This is changing the way to increasing manufacturing and backed use via western governments. PV solar cannot compete with wind electricity; however, at the longtime drastic enhancements are to be predicted. A long-term vision that new houses are blanketed with solar roofs is getting nearby. Solar structures have low protection (most effective cleansing) and can keep a few costs by way of replacing traditional roofing systems.

In the Caribbean, PV solar systems are already getting close to the price of producing electricity from fossil assets because of the intense sunshine and high cost of diesel; once the production price of PV sun structures further decreases, they’ll create savings his or her owners. This will likely result in a massive leap forward.

An even extra awarding supply of solar energy inside the Caribbean is the solar water heater. They produce ample warm water, and the established cost may be as low as 800 US$ for a 50-gallon gadget. In many instances, they pay for themselves in 2-three years. Yet, they may be far from popular. Awareness is the difficulty,

A thing precise to sun systems inside the Caribbean is safety towards hurricanes. In affected regions, the right measures want to be taken. PV systems ought to best be included with plywood panels, prepared to healthy. Solar water heaters have to either be protected or taken out in case of a storm. While all this requires attention in designing the setup, the good information is that the related price isn’t sizeable.


Using water force as an energy source is not new. Some international locations, inclusive of Canada, depend heavily on hydro energy. Clearly, the availability is limited to precise regions. And to make green use of hydroelectricity, the dimensions have to be enough. While the contribution of hydro is vital, it isn’t anticipated to belong to the main circulate in phrases of competitive growth of inexperienced power on a global basis. In the Caribbean, there are options, but the cost can be a prohibitive aspect.

Earth warmth based on the 9000° F internal earth temperature and regularly reduces in temperature towards the surfaces. However, the temperature near the surface varies greatly. Rainwater that sips in deeper parts of the earth receives warmth and is called a geothermal supply. In a few parts of the world, this water reveals its way again to the floor via cracks and faults, together with geysers (i.E. In Iceland) and hot springs.

As with solar energy, the issue is how to faucet that truly limitless source of green electricity. In maximum instances, the trick is to drill to find and get entry to the geothermal source. The hot water can then be used each direct and in geothermal power plants, consisting of 3 sorts. Steam can directly be used to generate strength with a dry steam generator.

Water between 300-seven-hundred°F may be used in a Flash Power Plant, where warm water is flashed into steam, Water with a temperature as low as 220°F may be utilized in a Binary Power Plant, in which the recent water circuitously produces steam from a fluid with a lower boiling point using warmness exchangers. The used water is fed back into the supply for reheating. It is renewable in an experience, as the available warmness potential has its limits.
