IRENA Report Examines Renewables’ Potential to Solve Water, Food and Energy Challenges

January 2015: A report titled 'Renewable Energy in the Water, Energy and Food Nexus,' which was released by the International Renewable Energy Agency (IRENA), finds that renewable energy has the potential to generate significant water savings, increase long-term food sustainability and bolster energy security.

The report highlights how renewables help ease the trade-offs among the water, agricultural and energy sectors through heightened water conservation, availability, accessibility and quality.

As one of many example cases from around the world presented in the report, the Gulf Cooperation Council's (GCC) renewable energy plans are highlighted as having the potential to reduce the power sector's water withdrawals by 20%. In agricultural supply chains, the report argues renewables can lower cost volatility, and in the energy sector the authors note that renewable processes and technologies are less resource-intensive.

The report also records renewables' added benefits of cutting pollution, fossil-fuel dependency and greenhouse gas (GHG) emissions. In addition to explaining the role of solar, wind, geothermal, hydropower and related technologies in solving these interconnected challenges, the authors dedicate a section to bioenergy. They find that sustainably and efficiently managed bioenergy production and use can also advance water, energy and food security.

The report was released on the margins of the World Future Energy Summit and International Water Summit, held in January 2015 in Abu Dhabi, United Arab Emirates (UAE). [IRENA Press Release] [IRENA Publication Webpage] [Publication: Renewable Energy in the Water, Energy and Food Nexus]

Caribbean Energy Security Summit Commits to Energy Transition

January 2015: Twenty-six countries, together with seven regional and international organizations, have released a joint statement in support of the transformation of the energy systems of Caribbean countries.

The signatories of the statement, signed during the Caribbean Energy Security Summit, commit to pursuing comprehensive approaches to an energy transition toward “clean sustainable energy for all” and reforms that support the creation of favorable policy and regulatory environments for sustainable energy.

The Summit, which was co-hosted by the US Department of State, the Council of the Americas and the Atlantic Council, brought together finance and private sector leaders from the US and the Caribbean, and representatives of the international community. The event showcased the initiatives under the Caribbean Energy Security Initiative (CESI) in the areas of improved governance, access to finance and donor coordination, and featured discussions by partner countries on comprehensive energy diversification strategies.

During the event, the US Government announced enhanced support for technical assistance and capacity-building programs in the Caribbean, through the Energy and Climate Partnership of the Americas (ECPA) initiative, among others, with the aim of promoting a cleaner and more secure energy future in the region. Caribbean leaders agreed to pursue comprehensive energy diversification programs and facilitate the deployment of clean energy.

Furthermore, presentations and updates were provided by, inter alia: Caribbean leaders on energy sector goals; the World Bank on a proposed Caribbean Energy Investment Network for improved coordination and communication among partners; and the US Overseas Private Investment Corporation (OPIC) on a new focus on clean energy project development in the Caribbean, which includes US$43 million in financing for a 34 MW wind energy project in Jamaica.

Highlighting the role of the Organization of American States (OAS) in supporting the transition to sustainable energy in the Caribbean, OAS Secretary General José Miguel Insulza said the past five years had seen an “unprecedented push” in the Caribbean toward the development of the region's renewable energy sources, noting this was “doubly impressive” “in a time of low oil prices.”

The Summit, which took place on 26 January 2015, in Washington, DC, US, is part of CESI, launched by US Vice President Joseph Biden in June 2014. The regional and international organizations signing the statement were the Caribbean Community (CARICOM) Secretariat, the Caribbean Development Bank, the EU, the Inter-American Development Bank (IADB), the International Renewable Energy Agency (IRENA), the OAS and the World Bank.

The joint statement was also signed by the Governments of Antigua and Barbuda, Aruba, Bahamas, Barbados, Belize, Canada, Colombia, Curacao, Dominica, Dominican Republic, France, Germany, Grenada, Guyana, Haiti, Jamaica, Mexico, New Zealand, Spain, St. Kitts and Nevis, St. Lucia, St. Vincent and the Grenadines, Suriname, Trinidad and Tobago, United Kingdom, and the United States.

Caribbean Energy Summit 2015: US Announce Investments in Energy Security for Caribbean Countries During First-Ever DC Summit

The Obama administration recently hosted the first Caribbean Energy Security Summit to support the region's improved governance, access to finance and increased donor coordination for the energy sector.

Vice President Joe Biden has led the issue of Caribbean energy security and said the Obama administration considers the topic as a primary issue.

“This is extremely important to us. It's overwhelmingly in the interest of the United States of America that we get it right, and that this relationship changes for the better across the board,” Biden said.

Biden added that the low oil prices have given little breathing room for governments, but there are alternatives. He mentioned renewable energy as an affordable source in addition to developing wind and solar energy.

“Meanwhile, we're in the midst of a seismic shift in the global economy: the ascendancy of the Americas as the epicenter of energy production in the world,” Biden said. “We have more oil and gas rigs running in the United States, than all the rest of the world combined. Mexico, Canada and the United States is the new epicenter of energy — not the Arabian Peninsula. It is the new epicenter of energy in the 21st century.”

The vice president called for an integrated North America to promote energy security since the U.S. wants Caribbean countries to “succeed as prosperous, secure, energy-independent neighbors — not a world apart, but an integral part of the hemisphere, where every nation is middle class, democratic and secure.”

Biden further stressed the purpose of the summit is not to “put up another solar panel or sign another gas contract” but to help countries establish protocol to attract private-sector investment. The vice president, however, acknowledged that countries have to confront corruption by having clear and transparent rules.

The U.S. created the Overseas Private Investment Corporation (OPIC), which will focus on developing energy projects for the Caribbean. Biden announced $90 million from the OPIC will be funded to Jamaica for wind projects.

The Caribbean Energy Security Summit is a “key component” to Biden's Caribbean Energy Security Initiative, which he announced in June 2014.

A joint statement on Monday had participating countries and regional and international organization agreeing for the Caribbean to make “necessary and specific reforms” that include efforts for sustainable and clean energy technologies. The participants also stated their commitment to exchange data and energy information.

The Jan. 26 summit from Washington, D.C. included governments from Antigua and Barbuda, Aruba, Bahamas, Barbados, Belize, Canada, Colombia, Curacao, Dominica, Dominican Republic, France, Germany, Grenada, Guyana, Haiti, Jamaica, Mexico, New Zealand, Spain, St. Kitts and Nevis, St. Lucia, St. Vincent and the Grenadines, Suriname, Trinidad and Tobago and the United Kingdom. The Caribbean Community (CARICOM) Secretariat, Caribbean Development Bank, European Union, Inter-American Development Bank Group, International Renewable Energy Agency, Organization of American States and the World Bank Group also participated.

UNEP Manual Provides Guidance on Valuing SIDS’ Ecosystem Services

26 January 2015: The UN Environment Programme (UNEP) launched a manual on calculating the value of ecosystems in small island developing States (SIDS), with the aim of supporting a transition to a green economy. The manual underscores the importance of accounting for the contribution of ecosystem services to human well-being in order to quantify and value these benefits.

The ‘Guidance Manual on Valuation and Accounting of Ecosystem Services for SIDS' highlights the interdependence between SIDS' economies and the natural environment. In Antigua and Barbuda, Anguilla, Seychelles and Vanuatu, 50% of gross domestic product (GDP) comes from the tourism industry, according to the manual. In the Federated States of Micronesia (FSM), fisheries contribute 10% of GDP while 52% of Grenada's exports come from tuna, albacore, cocoa beans and nutmeg.

The manual provides a step-by-step methodological approach to select, design and implement island ecosystem services valuation and accounting exercises, and shares case study examples of accounting and valuation techniques. For instance, a 1% increase in the number of coastal protected areas is associated with a 2.9% increase in international coastal tourism arrivals. The manual also provides guidance on designing a payments for ecosystem services (PES) scheme in SIDS, using the example of Palau's Green Fee.

The manual aims to support policymakers in achieving sustainable development, taking into consideration SIDS' unique environmental, socio-economic and capacity issues. The manual emphasizes that “there is no simple solution” to valuing and accounting for SIDS' ecosystem services, emphasizing that economic valuation and accounting techniques depend on the category of island ecosystem services (cultural, provisioning or regulating) and the island's type of economic policy.

UNEP launched the manual at an event marking the close of the 2014 International Year of SIDS. [Publication: Guidance Manual on Valuation and Accounting of Ecosystem Services in Small Island Developing States] [UNEP Press Release] [UNEP Publications Website]

Water Power In The Andes

Going to work these days is always a bit of a thrill for me–often more than I care for. It means crossing a 15,000 foot (4,570 m) pass over the Bolivian Andes and snaking down a muddy one lane road carved into the face of immense cliffs. The Most Dangerous Road in the World was the title of an old National Geographic article…

World's Largest Solar Machine

Actually I'm entering the world's biggest solar energy machine-the Amazon basin. Towering glacier-topped 20,000 foot (6,100 m) mountains are clearly visible from our tropical water power demonstration site. This mountainous east-facing wall so thoroughly captures the Amazon moisture that the western side-the Atacama desert-is the driest place in the world. Sometimes rain only falls there a few times during an entire lifetime.

But on this side, it's just the opposite. Uncounted streams and waterfalls abound, some falling hundreds of feet directly onto the roadway! About 80 people die yearly on this short section of road, since it is very narrow and slippery. Vehicles that slip off the road can simply disappear into dense vegetation a thousand feet (300 m) below. It's incredible to think that this is the only road into a tropical part of Bolivia that's the size of Texas.

It's a relief to arrive in the lovely 5,500 foot (1676 m) high town of Coroico, near our demo site. Green hillsides are covered with coffee, citrus, and bananas. This also happens to be the home of Bolivia's traditional coca leaf production, so the area is much affected by the U.S. “War on Drugs.”

Campo Nuevo – Meeting People's Needs

Our family-sized appropriate technology organization, Campo Nuevo, was started to better the lives of Bolivia's rural poor. We teach them how to use their local natural resources for energy. We show them how easy it is to employ the abundant small local sources of water power to improve their lives. This can help make it possible for them to remain on their land and in their own communities.

We are working with Aymara speaking native Americans, one of the largest and most intact indigenous cultures in the Western Hemisphere. Notable for having withstood the Incan conquest, and later the Spaniards, the Aymaras are now succumbing to the pressures of modern global economics. Like rural people all over the “third world,” they are being forced to relocate simply to survive. They usually migrate to a desolate l3,000 foot (3,960 m) suburb of La Paz, in order to compete for unskilled, low paying, and often temporary jobs.

A New/Old Solution

Although they may not realize it, what visitors to our demonstration site see is not actually new. It's actually a revival of the now nearly forgotten traditional use of water power. For thousands of years before the invention of centrally-generated electricity, water power was employed to directly run machines, something it does very well.

What is new is the development of a modern low-cost turbine specifically for this purpose-a “motor” driven by water power. We call it the “Watermotor.” It can provide the energy to drive a variety of machines, replacing the mid-sized electric motors upon which nearly all modern production depends.

Lester Pelton, who invented the pelton wheel, produced a variety of these water powered motors and they were in use before l900. They were used to power individual machines – he even used one to run a sewing machine! The direct drive hydro units were replaced by electric motors after the popularization of centrally produced electricity.

Few people realize how closely rural poverty is related to the lack of machines necessary for local production and services. In the third world, the power grid is usually confined to cities and large towns. Rural people still use muscle power as everyone did in the past, and they do without electric lights. The need to generate cash to buy anything they don't produce themselves causes a focus on cash crops. This further reduces their self-sufficiency, encouraging a downward spiral towards dependency on a system that cannot be depended upon!

Demo Site
At our new Campo Nuevo demonstration site, we are featuring practical machines, directly powered by water. There are woodworking tools, air compressors, grain mills and an auto alternator to charge batteries and provide lighting. This is switched on when mechanical power is not being used, run by the same belt drive that powers the tools.

The main attraction at our site is our Campo Nuevo Watermotor driving a multipurpose woodworking unit. The machine is suitable for producing doors, window frames and furniture-necessities usually purchased from the city. It processes locally produced lumber instead of wood carried up from the Amazon forest.

The Watermotor at our demonstration site is provided with power from a water source located 60 feet (18.3 m) above the machine by 160 feet (50m.) of lightweight 4″ plastic pipe.

We get 1.3 h.p at 1850 r.p.m.s using 115 gal. (440 l.) per minute with the Watermotor Model 90 , and 2.5 h.p. at 1000 r.p.m.s with Model 150 using about 225 gal. (850 l.) per minute.

At the heart of our Watermotor turbine is a Swedish designed 4 jet Turgo wheel and a patented Turgo control system which provides the same instant on/off power control as an electric motor.

Unlike an electric motor, the Watermotor costs nothing to operate and can't be “burned out” from hard use.

It's Not Easy

Not much of this area is served by roads or the power grid. The U.S. owned (and U.S. priced) power generating system has little incentive to provide long distance lines to a widely scattered and typically impoverished rural population. Water power is the sole available practical source of energy to run machines. There is not a good wind resource in the mountain valleys and PV is just not economical, compared to the abundant water power here.

There are major obstacles to the introduction of unfamiliar technology to an indigenous population that has traditionally used no machines of any kind. These people have little money to invest in anything that does not promise a practical return. In addition to this, the Aymaras are unlikely to be reached by advertising in the newspapers from La Paz. This is why we felt that a local demonstration site was necessary.

Other problems are encountered when machines, however useful, need to be “professionally” installed, maintained or repaired. Such services are frequently unreliable, hard to come by in rural areas, and expensive when available.

Keep It Simple

In designing the Watermotor system, we have tried to overcome these obstacles as much as possible. It is designed to be user-installed, maintained, and repaired because of the difficulties in finding competent, honest and reliable technical services in rural areas of Bolivia. Because the Watermotor is locally produced from common materials, most parts can be easily replaced.

The efficiency of direct drive water power is a big advantage. A surprisingly small amount of water falling a short distance can produce the 0.5 to 5 h.p. of mechanical power required by most common machines. This means that many potential water power sites are available, and a minimum of civil engineering is required.

Of course the power output of the Watermotor depends on the fall and the amount of water that one uses to run it. Here are some examples of other possible installations and the energy output that they would produce:

A Watermotor Model 90 would produce:
1.5 h.p.at 2365 r.p.m.s with a 100 ft. (30.5 m.) fall and 75 gal.(284 l.) per minute
3 h.p. at 2900 r.p.m.s with 150 ft (46 m.) fall and 100 gal.(378 l.) per minute

A Model 150 will produce:
2 h.p. at 865 r.p.m.s with a 40 ft. (12.2 m.) fall and 250 gal. (950 l.) per minute
3 h.p. at 950 r.p.m.s with a 75 ft. fall (23 m.) and 200 gal.(750 l.) per minute
5 h.p. at 1366 r.p.m.s with a 100 ft.(30.5 m.) fall and 250 gal.(950 l.) per minute

The Watermotor itself is very simple to operate, and maintain. It functions efficiently in a variety of water power situations. By merely experimenting with easily changed water jets of different sizes, it is possible to vary maximum power output. This also allows the turbine to maintain efficient output over seasonal water flow variations. A single control handle diverts water away from the Turgo wheel, instantly cutting power.

The Watermotor can be used to drive most stationary machines normally driven by an externally-mounted electric motor or small gasoline engine in the 0.5 to 4 horsepower range.

Machines being driven by the Watermotor can be mounted directly on the turbine housing or beside the turbine. The tools are connected to the Watermotor by a standard belt, which limits the distance between the two parts of the system.

Make the Comparison

How does the Watermotor stack up against the competition? I asked a couple of renewable energy experts to give me the rough cost of a wind or photovoltaic system capable of producing 2 1/2 hp of mechanical energy 24 hours a day, including installation in rural Bolivia and technical expertise for maintenance and repair.

Richard Perez of Home Power said, “Well, the photovoltaic panels alone will cost about US$35,000. And the requirement for 24 hour power at that level means a very large battery bank which will bring the system cost up to around US$70,000. And we still need to add small stuff like racks, inverter, and controls. Overall, I'd say about US$80,000. It really points out how cheap hydro is.

Mick Sagrillo, North American wind power guru, said, “My guess, using off the shelf equipment, would be that you'd need a Bergey Excel. While it's larger than what's needed, it's cheaper than putting up several smaller turbines. Cost for genny and controls is about US$19,000, less tower, wiring, batteries, and balance of systems components. Total system cost would be roughly US$35,000. The one message I always deliver at my wind power workshops is that if anyone has a good hydro site, they're in the wrong workshop. While wind is cheaper than PV, it's no comparison for a hydro site with a 100 percent capacity factor.”

Now, this is not a scientific comparison, and these are admittedly rough figures. But the Watermotor can do this-produce 2 1/2 hp continuous-with a system cost of less than US$2,000. It's user installable and maintainable (two lube points), and easily repairable. It has only one moving part and is immune to damage from hard use. Consider also the sources of PV and wind equipment (all imported) and the possibility of damage from misuse or poor maintenance.

Watermotor type designs were abandoned about l00 years ago in the developed world in favor of electric motors. To the best of my knowledge, there are no machines equivalent to the Watermotor being produced today. Generally, very few products, no matter how useful, are produced with the aim of promoting self-sufficiency among the rural poor.

Making It Available

The best advertisement for our water driven machines is for them to be seen hard at work by the many people passing the demo site daily. Woodworking and grain milling machines in particular have a substantial per-hour cash value. Because the Watermotor is immune to damage from hard use, it is suitable to rent or lease. At current rates, the entire cost of a Watermotor installation should be recovered in only a few months.

We expect visitors to our demonstration site to have their own ideas about how they can use the Watermotor. The success of this site will provide us with knowledge and incentive to build similar sites in other parts of Bolivia.

While Bolivia is especially rich in water power resources, many other parts of the world have similar conditions, and similar needs. We would like to see this clean, self-renewing, and easy to use natural resource made available to all.

Side Event: The Ocean We Need for The Future We Want

The Global Ocean Commission and the Permanent Mission of Sweden to the United Nations are happy to invite you to their side event on Wednesday 21 January, lunch time, on the margins of the UN BBNJ negotiations.

Side Event: The Ocean We Need for The Future We Want

Wednesday, 21st January 2015

Conference Room 5

13.15-14.45

(Light lunch will be provided)


David Miliband, Co-chair Global Ocean Commission, President and CEO of the International Rescue Committee (IRC) and former UK Foreign Secretary

Lisa Emelia Svensson, Ambassador for Ocean, Seas and Fresh Water, Ministry of the Environment, Government Offices of Sweden

Shorna-Kay Richards, Minister and Deputy Representative, Permanent Mission of Jamaica to the UN

Max Diener, Legal Advisor, Ministry of Foreign Affairs of Mexico

The Global Ocean Commission report (www.globaloceancommission.org) released in June 2014 contains eight proposals directly related to the governance, sustainable use and conservation of marine biodiversity in Areas Beyond National Jurisdiction. The convening of the Global Ocean Commission came from the realization that the context of modern ocean governance had changed markedly since UNCLOS was negotiated.

This side event will consider these solutions and proposals which the Global Ocean Commission has tabled for a future healthy ocean in the context of the BBNJ negotiations and the potential new implementing agreement.

The Co-chair of the Global Ocean Commission will give insights to their deliberations drawn from the diverse backgrounds of the Commissioners, and will reflect on the compelling evidence which lead them to advocate strongly in their report for a new UNCLOS Implementing Agreement for the high seas.

The other eminent speakers will focus on the intimate linkages between the BBNJ process and the potential impact the outcome of these negotiations will have on the other ocean issues.

Further information can be obtained from Lisa Emelia Svensson (lisa.svensson@gov.se) or Rémi Parmentier (remi.parmentier@globaloceancommission.org)
