Bringing power and progress to Africa in a financially and environmentally sustainable manner

EXECUTIVE SUMMARY: The future of electricity supply and delivery on the continent of Africa represents one of the thorniest challenges facing professionals in the global energy, economics, finance, environmental, and philanthropic communities. Roughly 600 million people in Africa lack any access to electricity. If this deficiency is not solved, extreme poverty for many Africans is virtually assured for the foreseeable future, as it is widely recognized that economic advancement cannot be achieved in the 21st Century without good electricity supply. Yet, if Africa were to electrify in the same manner pursued in developed economies around the world during the 20th Century, the planet’s global carbon budget would be vastly exceeded, greatly exacerbating the worldwide damages from climate change. Moreover, due to low purchasing power in most African economies and fiscal insolvency of most African utilities, it is unclear exactly how the necessary infrastructure investments can be deployed to bring ample quantities of power – especially zero-carbon power – to all Africans, both those who currently are unconnected to any grid as well as those who are now served by expensive, high-emitting, limited and unreliable electricity supply. With the current population of 1.3 billion people expected to double by 2050, the above-noted challenges associated with the African electricity sector may well get substantially worse than they already are – unless new approaches to infrastructure planning, development, finance and operation can be mobilized and propagated across the continent. This paper presents a summary of the present state and possible futures for the African electricity sector. A synthesis of an ever-growing body of research on electricity in Africa, this paper aims to provide the reader a thorough and balanced context as well as general conclusions and recommendations to better inform and guide decision-making and action.

Carbon Free Boston: Energy Technical Report

Part of a series of reports that includes: Carbon Free Boston: Summary Report; Carbon Free Boston: Social Equity Report; Carbon Free Boston: Technical Summary; Carbon Free Boston: Buildings Technical Report; Carbon Free Boston: Transportation Technical Report; Carbon Free Boston: Waste Technical Report; Carbon Free Boston: Offsets Technical Report; Available at http://sites.bu.edu/cfb/INTRODUCTION: The adoption of clean energy in Boston’s buildings and transportation systems will produce sweeping changes in the quantity and composition of the city’s demand for fuel and electricity. The demand for electricity is expected to increase by 2050, while the demand for petroleum-based liquid fuels and natural gas within the city is projected to decline significantly. The city must meet future energy demand with clean energy sources in order to meet its carbon mitigation targets. That clean energy must be procured in a way that supports the City’s goals for economic development, social equity, environmental sustainability, and overall quality of life. This chapter examines the strategies to accomplish these goals. Improved energy efficiency, district energy, and in-boundary generation of clean energy (rooftop PV) will reduce net electric power and natural gas demand substantially, but these measures will not eliminate the need for electricity and gas (or its replacement fuel) delivered into Boston. Broadly speaking, to achieve carbon neutrality by 2050, the city must therefore (1) reduce its use of fossil fuels to heat and cool buildings through cost-effective energy efficiency measures and electrification of building thermal services where feasible; and (2) over time, increase the amount of carbon-free electricity delivered to the city. Reducing energy demand though cost effective energy conservation measures will be necessary to reduce the challenges associated with expanding the electricity delivery system and sustainably sourcing renewable fuels.Published versio

Local Solutions to Global Problems: Policy Choice and Regulatory Jurisdiction

This paper considers the efficiency of various types of environmental regulations when they are applied locally to pollutants whose damages extend outside the jurisdiction of the local regulator. We draw on examples from state- and city-level efforts to address climate change by enacting policies to reduce greenhouse gases. While previous work has noted the possibility for leakage, whereby the polluting sources move outside the jurisdiction of the regulation in order to escape it, we note an additional problem when policies are targeted downstream at consumers of goods whose production creates pollution. Specifically, we show how consumer-based policies can be circumvented by a simple reshuffling of who is buying from whom. We argue that the leakage and reshuffling problems are most pronounced with more flexible or market-based regulations. We conclude that localities may have the most effect on global pollutants when they enact efficiency standards or targeted subsidies.

Large Scale Deployment of Renewables for Electricity Generation

Comparisons of resource assessments suggest resource constraints are not an obstacle to the large-scale deployment of renewable energy technologies. Economic analysis identifies barriers to the adoption of renewable energy sources resulting from market structure, competition in an uneven playing field and various non-market place barriers. However, even if these barriers are removed, the problem of ‘technology lock-out’ remains. The key policy response is strategic deployment coupled with increased R&D support to accelerate the pace of improvement through market experience. The paper suggests significant contributions from various technologies, but does not assess their optimal or maximal market share

Electric vehicles – effects on domestic low voltage networks

Electric Vehicles (EV) charging from a domestic power socket are becoming increasingly popular due to their economic and environmental benefits. The large number of such vehicles presents a significant additional load on existing low voltage (LV) power distribution networks (PDN). Evaluating this impact is essential for distribution network operators (DNO) to ensure normal functioning of the distribution grid. This research uses predictions of EV development and penetration levels to create a stochastic model of aggregate charging demand in a neighbourhood. Combined with historic distribution substations data from the Milton Keynes, UK total loads on the distribution transformers are projected. The results show significant overloading can occur with uncoordinated charging with just 25% of EVs on the road. The traditional way to solve this problem would be upgrading the transformer; however, that could be avoided by implementing coordinated charging to redistribute the load

Comparing German and US Energy Transitions: Centralized vs. Decentralized Government Approaches

The German Energiewende (“energy transition”) is often credited with being the most ambitious renewable energy transition in the world. Germany’s rapid transition is mainly led by their Renewable Energy Act of 2000, which has been amended several times in order to remain relevant during changing conditions. In contrast, the United States’ energy transition seems stagnant and lacks an overall direction from the Federal Government. Despite this, the United States is making progress towards implementing renewable energy technologies due to the efforts of several states. Germany’s transition has experienced a number of challenges along the way, while the United States’ transition has benefited from the first-mover knowledge of Germany. This project will evaluate the two energy transitions using simple and complex indicators and determine which approach has been most effective: Germany’s centralized approach or the United States’ decentralized approach. It will then determine if either approach is sustainable. This project determined that Germany’s centralized approach appears more effective. Additionally, results of a System Improvement Process (SIP) analysis shows that renewable energy cannot be developed sustainably at this time due to a number of barriers

China and the United States—A Comparison of Green Energy Programs and Policies

[Excerpt] China is the world’s most populous country with over 1.3 billion people. It has experienced tremendous economic growth over the last three decades with an annual average increase in gross domestic product of 9.8% during that period. This has led to an increasing demand for energy, spurring China to add an average of 53 gigawatts (gw) of electric capacity each year over the lastten years to its power generation capabilities. China has set ambitious targets for developing its renewable energy resources with a major push of laws, policies, and incentives in the last few years. The wind power sector is illustrative of China’s accomplishments, as installed wind power capacity has gone from 0.567 gw in 2003 to 12.2 gw in 2008, and China surpassed the United States in 2010 with over 41 gw of installed wind power capacity. Notably, however, approximately one-third of that capacity is not yet connected to the power grid. Plans already exist to grow China’s wind power capacity to 100 gw by 2020. A similar goal exists for the solar photovoltaic power sector which China intends to increase generating capacity from 0.14 gw as of 2009 to over 1.8 gw by 2020. A hold on large and medium-scale hydropower project development has been lifted, with a virtual doubling of hydropower capacity planned. Most recently, China pledged ahead of the Copenhagen talks in 2009 that 15% of total energy consumption will come from non-fossil fuel sources by the year 2020. The 12th Five Year Plan will encompass 2011 to 2015, and will further formalize the link to green energy with specific deployment goals and investment. China recognizes that developing its domestic renewable energy industry and building its manufacturing capacity will help it meet energy demands at home and win advantages in future export markets. The key piece of legislation in recent years for advancing renewable electricity in China is the Renewable Energy Law of 2005. The law was designed to “promote the development and utilization of renewable energy, improve the energy structure, diversify energy supplies, safeguard energy security, protect the environment, and realize the sustainable development of the economy and society.” Renewable energy is subsidized by a fee charged to all electricity users in China of about 0.029 cents per kilowatt-hour, and was originally based on the incremental cost difference between coal and renewable energy power generation. However, energy efficiency and conservation are officially China’s top energy priority. These are considered the “low-hanging fruit” in the quest to reduce energy use and cut demand. Energy conservation investment projects have priority over energy development projects under the Energy Conservation Law of 1997, with government-financed projects being selected on “technological, economic and environmental comparisons and validations of the projects.” China is the world’s largest market for new construction, and new building standards have been in development since 2005 with national energy design criteria for residential buildings. In the power generation sector, many smaller, less efficient coal-fired power plants have been closed. In contrast to China, some argue that the United States does not have a comprehensive national policy in place for promotion of renewable energy technologies, with some observers saying that the higher costs of renewable electricity are not conducive to market adoption. However, for both countries, the reasons for increasing the use of renewable energy are diverse, and include energy security, energy independence, cleaner air, and more recently anthropogenic climate change, sustainability concepts, and economic development. Creating new, higher quality jobs could reasonably be said to be primary drivers of policy goals in both the United States and China
