  • Renewable Energy Farming Solutions in Nicaragua:Tecnosol

    Type: 
    Publication
    Publication date:
    Objective:

    Nicaragua is an energy-poor and agriculture-dependent country. While the cattle and dairy sector is a dominating force among the country’s agricultural sectors, its productive output is remarkably low compared to that of neighbouring countries. Inefficient herding and farm management leads to hygiene issues, high loss of livestock and low production. Most small scale farmers lack access to modern energy. The sector is in dire need of productivity improvements to remain competitive in the region. 

  • Record Breaking Year for Renewable Energy: More renewable energy capacity for less money

    Type: 
    News
    Publication date:
    Objective:
    Cross-sectoral enabler:

    REN21 published its Renewables 2017 Global Status Report (GSR), the most comprehensive annual overview of the state of renewable energy. 

    Additions in installed renewable power capacity set new records in 2016, with 161 gigawatts (GW) installed, increasing total global capacity by almost 9% over 2015, to nearly 2,017 GW. Solar PV accounted for around 47% of the capacity added, followed by wind power at 34% and hydropower at 15.5%.

  • Vietnam Institute of Geosciences and Mineral Resources

    Type: 
    Organisation
    Country of registration:
    Vietnam
    Relation to CTCN:
    Network Member

    VIGMR, established since 1965 under MONRE, is leading research institute in Vietnam on Geosciences and Mineral Resources. With mandate to boost sustainable national development by geoscientific and technological advancement, VIGMR conducts researches, survey and development of georesources, R&D and achievements diffusion  corresponding to geohazards and global environment changes. Geopark, renewable energy, waste treatment, phytoremediation of environment, CO2 mineralization and other climate change technologies, and community-based capacity building are some focuses of VIGMR. 

  • Pumped hydroelectric energy storage

    Type: 
    Technology
    Objective:

    Next to the other energy storage technologies, such as phase change materials, batteries and CAES, pumped hydro is another option for energy storage. Pumped hydro storage uses two water reservoirs which are separated vertically. In times of excess electricity, often off peak hours, water is pumped from the lower reservoir to the upper reservoir. When required, the water flow is reversed and guided through turbines to generate electricity.

  • Soilless agriculture

    Type: 
    Technology
    Objective:

    Aeroponics

    Aeroponics is the process of growing plants in an air or mist environment without the use of soil or an aggregate medium (known as geoponics). Unlike hydroponice, which uses a liquid nutrient solution as a growin medium and essential minerals to sustain plant growth; or aquaponics which uses water and fish waste, aeroponics is conducted without a growing medium. 

  • Solar cooling and hybrid systems with heating and hot water

    Type: 
    Technology
    Sectors:
    Objective:

    Solar cooling technologies transform solar radiation to provide space cooling and refrigeration services. Air conditioning in buildings has traditionally been provided by air conditioners using electrically driven vapour compression chillers. These are responsible not only for GHG emissions, but also use CFCs and HCFCs and related compounds as refrigerant fluids, which also contribute to climate change and are known to deplete the ozone layer.

  • Solar water pumps

    Type: 
    Technology
    Sectors:
    Objective:

    A reliable and clean water supply is an essential need but a large number of people currently lack this basic provision. Solar water pumps is a socially and environmentally attractive technology to supply water. Especially if the need for water is in remote locations which are beyond the reach of power lines, solar power is often the economically preferred technology.

  • New CTCN/UNIDO Call for Proposals: Water and energy efficiency and self-generation plan in the Solomon Islands

    Type: 
    News
    Publication date:
    Objective:

    Solomon Islands comprise hundreds of islands.  Solomon Islands Water Authority (SW), a state-owned enterprise, is mandated to operate as the provider of municipal water and wastewater services. About 95% of total installed capacity of electricity generation in Solomon Islands is based on fossil fuels, and the balance 5% is through renewable energy sources. The electricity tariff of Solomon Islands is one of the highest in the Pacific since a major share of electricity in the Islands is met through fossil fuels. 

  • Measuring the Effect of Transaction Costs for Investment in Irrigation Pumps: Application of Unobserved Stochastic Threshold Model to the Case of Nigeria

    Type: 
    Publication
    Publication date:
    Objective:
    Sectors:

    Small-scale private irrigation schemes have been the driving force behind the expansion of irrigated areas in Nigeria, despite government efforts to promote large-scale public irrigation schemes. This article empirically assesses the effect of unobserved transaction costs for Nigerian farmers" when investing in irrigation pumps, using the baseline survey data for the Second Fadama Development Program (Fadama II).
