CURRENT SITUATION AND PROSPECTS OF RENEWABLE
ENERGY SOURCES IN CUBA FOCUSING ON WIND ENERGY
Conrado Moreno Figueredo and Jose Augusto Medrano
Center for Study of Renewable Energy Technologies (CETER)

Abstract:
Over the latest years, Cuba’s electricity industry has undertaken relevant reforms. By 2005 the Government of Cuba
designed an energy development strategy known as Energy Revolution in Cuba. Distributed generation, electric gridrehabilitation, energy saving, energy education and the growing use of renewable energy sources become the spinal
column of this strategy. The Cuban strategy of developing the National Electric System establishes the tendency todecrease the share of thermal power plants burning oil. Such as other regions of the area, the country not yet possesses
the necessary sources of fossil fuels for its subsistence but if it is rich in renewable energy resources. In Cuba, it
constitutes a necessity to increase the use of all the types of renewable sources of energy and at the same time to elevate
the energy efficiency of the facilities. The reasons are of different nature: to reduce the dependence of the country of theimport fossil fuels what is very related with the energy sovereignty, to diminish the costs of the energy production due toeffect of the high prices of the fossil fuels, the high costs of the energy that it is distributed the users to achieve a more
efficient national economy and to diminish the negative effects on the environment caused by the use of the fossil fuels
among other causes. The renewable energy sources which appear in the Cuban archipelago and have an application
currently are: the wind energy, the thermal and photovoltaic solar energy, the small wind turbines and the biomass asenergy source fundamentally the sugar cane wastes. Among the renewable energy (RE) sources in the country, windenergy is considered as the most dynamic source in the first years of this new strategic design. In the last years, windenergy has been the RE source with major growth, from 2,1 MW in 2007 to 11,7 MW in 2010. Currently a wind park of
50 MW is in stage of implementation. The program by 2030 is focused to have 700 MW installed. Other renewableenergies possess ambitious plans for the near future such as photovoltaic connected to the grid, the sugar cane biomass
and the small hydro. The purpose of this work is to give a panoramic of the current situation of these renewable energy
technologies in exploitation and the perspective of each one of them, the laws that govern in the country supporting theuse of the renewable energy in these moments and the productive chain of the Cuban industry.

Abstract:
The German municipality of Dardesheim is well known as “town of renewable energy”. Dardesheim is a small nice town
having just 1.000 inhabitants. It is located in the eastern German bundesland of Sachsen-Anhalt. Renewable energies are by far
the most important industry of Dardesheim. On the roofs of the private buildings there are a lot of photovoltaic systems. The
local wind energy farm consists of 35 Enercon 2 MW-turbines and 1 Enercon-machine of 6 MW, in total an installed capacityof 76 MW, producing forty times more than the total electrical demand of the municipality. The photovoltaic installations areproducing actually about 100 % of the private households` electrical demand. Several inhabitants are financial shareholders of
the combined renewable energy farm. Nearly everybody is profiting from the results, privately or in his role as member ofdifferent social groups of the town. The outcome of the energy farm leads to an increasing local purchasing power.
The organisers are advertising for increasing financial participation in the wind farm by the citizens: During the first eight
years since erection the annual interest rate for them was between 8 – 10 % depending of the results. The wind farm issponsoring local cultural and social groups, for instance sports groups, young and senior peoples activities or for instance thelocal brass orchestra which by now five times won the Germans brass orchestras championships. Sponsoring is also granted toan annual rock music festival organised by a group of young musicians. And they advertise for wind energy on their event
posters. Each second month the energy farm publishes a newspaper for the people of Dardesheim and the villages around freeof charge. These newspapers are also published on the website of the energy farm: www.generalwind.com, which attracts
increasing numbers of visitors by now in 13 different languages.
A new idea is the combination of the wind farm with a neighboured 80 MW hydro storage station, so that not only
Dardesheim, but also about 10.000 people around can be supplied by 100 % renewable energy even if actually wind is not or
not sufficiently blowing. During high wind speeds the water is pumped up to a higher level – at low winds water runs down andreproduces electricity via two 40 MW hydro turbines. A model of the control panel of that renewable virtual power plant can beseen in the town hall of Dardesheim. There interested people can see and understand: The conventional energy prices areincreasing and the costs of renewable energy are decreasing and will be in future more and more the cheaper alternative.
Renewable energies are supporting the regional economy. In Dardesheim the people are feeling: “This fits very well to ourlandscape and to our future political expectations.

Paving the way to large-scale wind power developments:
Morocco’s pre-COP22 policies

Abstract:
With only 850 MW of capacity auctioned in 2016, the Moroccan Wind Energy Initiative of ONEE provided the world’s
lowest wind energy costs. At 3.0 ?cent/kWh without support mechanisms and close to 70% of the total investment in local
contents, the industry is on track to reach even lower wind energy prices in the future. Attributed to a consortium linking
Nareva -a local developer and equity investor- with Enel Green Power (EGP) and Siemens, the deal pitching four othercompeting international consortiums was judged on price and plans for local manufacture. As a result, and in order to serve
regional export markets as well, Siemens unveiled a rotor blade factory near Tangier Morocco, which is to start operating in2017. Considering the rather limited size of the wind power auction, Morocco leveraged its wind development experiencebacked by future wind potentials quite well. From an operational wind power capacity of 795 MW -whose largest share is
installed on the Saharan trade windblown coastline- ONEE’s integrated wind energy initiative consecrated years ofexperimentations with various wind development frameworks. These were aimed at maximizing wind project outcomes while
minimizing costs as well as financial exposures. A thorough review of the country’s renewable energy policies pertaining towind energy developments ahead of its chairmanship of the COP22 conference which will take place from 7-18 November
2016 in Marrakech will demonstrate the learning curve which has been acquired. A mix between concessionary public and fullprivate wind energy developments based on Morocco’s Renewable energy law 13-09 took advantage of industrial offset
policies that provide state of the art facilities to manufacturers. It is only through the establishment of a sustainable windindustry of which the Siemens blade factory in Tangier is the first step that a well-interconnected grid to neighboring markets
backed by an efficient generation mix will enable the country to tap into its significant wind energy potential. For this tohappen, a High Voltage Direct Current (HVDC) transmission line will provide a much needed effect of scale. The Sahara Wind
project’s 5 GW-HVDC efficient long transfer line will also open the access of the Sahara trade winds to a regional wind power
dispatch. Sound, inclusive renewable energy policies are therefore of utmost importance in this process.

Abstract:
Wind Desalination-wind hydraulic pumps-Off Grid-Agricultural- RO desalination- Minerals
The idea of climate drought along with constant increase in demand of natural resources is opening the horizon for a new
global market to be served. That includes but not limited to fresh water and minerals for the agriculture and chemicalindustries.
Challenges of the so called Water-Food-Energy Nexus provide commercial opportunities for the development ofinnovative solutions. These solutions combine existing commercially proven technologies to reduce financial andtechnology risk. We live in a world today where more than one billion people live in areas without water or where water
resources are scarce .Experts expect competition between cities, even between industry and agriculture sectors over theavailability of water resources, which can lead to international tension and conflicts over current diminishing resources.
Climate mapping shows current and predicted drought trends, as expected, recent drought conditions are set to continue.
New concepts are based on combining mature and innovative technologies. Pressurized hydraulic flow created in windfarms with wind driven pumps (wind pumps) used for rated electric power production by means of hydraulic motors or
turbines of constant speed and variable torque which actuates alternately/or simultaneously rated electric generators asfunction of wind power availability.
Use of positive displacement pumps driven by rotors of fixed pitch blades for maximum capture of wind power enables
the attainment of tip speed ratio in range of high power coefficient by means of the pressurized hydraulic flow of windfarms..
Another application of wind farms with wind driven pumps is for creation of variable hydraulic flow of fixed pressure asfunction of wind power availability which may be used for water elevation as well as for the desalination of salt water
solutions by reverse osmosis.
