Challenges to Future Energy Development WorldwideChallenges to Future Energy Development WorldwideFuture energy development faces great challenges due to•Increasing standards of living worldwideIncreasing standards of living worldwide•Demand for cleaner energy associated with less pollution•Depletion of fossil fuelDepletion of fossil fuelWithout energy, the infrastructure which forms the basis of development  would collapse: agriculture, transportation, p p g , p ,information technology, communication and most of the basic needs of life depend on energy.

Ghana’s Energy ChallengesWith an expanding economy and growing population, Ghana faces major challenges in providing: the required amount of

Renewable  Energy Resources in Ghanal llFuel Cell

The technology involves the conversion of chemical hydrogen and oxygen into water and in the process generate electricity Thisoxygen into water and in the process generate electricity. This holds considerable potential for addressing the energy needs of the world in the future 

Challenges to the Development of Renewable Energy in Ghanai i d blLimited Renewable Energy ResourcesRenewable energy sources in Ghana consisting of small and mini‐microhydro wind solar biomass and municipal solid waste wouldmicrohydro, wind, solar, biomass and municipal solid waste would only be able to supply between 380 and 500 MW delivering between 2,500 and 3,500 GWh competitively. p yThis will form about a tenth of the energy requirement of Ghana by 2020. More than 10% of renewable energy in the energy mix

Challenges to the Development of Renewable Energy in Ghana (Continue)(Continue)

•The potential of generating grid electricity from Solar PV is limited by capital rather than resource.•Wind may have the largest capacity for development among the 

ti d h th t ti l f t ib ti i ifi tl t idoptions and has the potential of contributing significantly to grid power by about 200‐300 MW producing 600 GWh

Cost per Kilowatt HourOne of the critical challenges to the adoption of renewable energy sources is the cost per unit to consumers compared with energy from other sources (fossil fuels).Th t f id t d l kWh i US$0 30•The cost of grid connected solar energy per kWh is over US$0.30 compared to US$ 0.04/kWh•The cost of a solar panel facility in Ghana is about US$ 7000/kWThe cost of a solar panel facility in Ghana is about US$ 7000/kW compared to US$500‐1000 for a gas fired thermal power plant

Challenges to the Development of Renewable EnergyChallenges to the Development of Renewable Energy 

Investment RiskThe volatility in the pricing  of oil and gas on the international market increases the risk of investment in renewable energy f iliti A d i h d b i d th i ffacilities.  A drop in hydrocarbon prices erodes enthusiasm for investment in renewable energy sector

Competing TechnologiesThere is intense competition to achieve hegemony within the sub sectors of the renewable energy market. In biofuels, lobbyists for a corn‐based solution vie with those championing cellulose, ethanol, bi di l Withi th l k t t ti lbiodiesel. Within the solar market, concentrating solar power systems compete with the much more popular photovoltaic systemssystems

i i di h i f f ili i dcommunities regarding the constructing of facilities to produce renewable energy. Intermittent Nature of Renewable Energy and Storage DifficultiesIntermittent Nature of Renewable Energy and Storage DifficultiesMany renewable energy sources are often dismissed because they can not be stored and also because they are intermittent. Constraints to Biofuel DevelopmentThe development of an alternative to existing fuel requires policy di i d idirectives and strategies.The main constraints are: Feedstock availability, local processing capacity technology development relating to end use consumercapacity, technology development relating to end use, consumer acceptance of new fuel and cost competitiveness

Challenges to the Development of Renewable Energy (Continue)Feedstock for Biofuel ProductionDiff t f d t k d f bi f l d ti i diff tDifferent feedstock are used for biofuel production in different countries. The general trend is that countries choose feedstock plants which are already being produced on large scales locally andplants which are already being produced on large scales locally and which have other commercial value other than the production of fuel. In Ghana, Palm oil, Jatropha curcus and Sugar cane offer significant advantages for  biofuel production.

Cost Competitiveness of BiofuelThe biofuel market worldwide is not well developed and biofuelsThe biofuel market worldwide is not well developed and biofuelsare not competitive even with crude oil at US$73.00 per barrel. The global market for biofuel is politically driven and relies on tax rebates.

Conclusion

Renewable Energy can be harnessed to support and supplement ti l l H i ifi t t t h lconventional energy supply. However, significant cost, technology 

and attitudinal barriers need to be surmounted before any meaningful penetration could be achieved.meaningful penetration could be achieved.
