The use of electric vehicle (EV) has been widely recognized as an effective way to reduce greenhouse gas (GHG) emissions from transportation sector. However, the geographic difference of GHG emission reduction from EV deployment is seldom explored. This paper presents a study on the total GHG emissions generated from the life cycle of an EV (represented by Nissan Leaf) and an internal combustion vehicle (ICV) (represented by Toyota Corolla) for benchmarking on the potential emission reductions in the United States. The differences of electricity mix and driving style in each state are considered in the analysis. The results indicate a 43% GHG emissions reduction from ICV with the deployment of EV under the current average United States’ electricity generation scheme and transportation style. But the life cycle GHG emission reductions vary significantly from state to state in the U.S. Some states such as Indiana, Wyoming and West Virginia can only get 7237, 9501 and 9860 kg CO2 equivalent reduced, while some states such as Vermont, New Jersey and Idaho can get 57915, 57206 and 49039 kg CO2 equivalent GHG emissions reduced. This study can be useful in supporting future decision-making and strategy development for EV deployment in the U.S.

In terms of generation capacity, Victoria has about 12,500 MW, out of a National Electricity Market (NEM) total of over 46,000 MW. A bit over half of Victoria’s capacity is made up of the brown coal generators in the Latrobe Valley (Loy Yang, Hazelwood, Yallourn). Gas-fired generation (mainly large open-cycle peaking plants, designed to operate only in times of high demand) and hydro plants (mainly parts of the Snowy scheme) add about 20% each, with wind currently making up the balance of around 9% of installed capacity in Victoria. In terms of wind farm location across the NEM, installed capacity is predominantly located in Victoria and South Australia, and to a lesser extent in Tasmania, with very small amounts in New South Wales and Queensland. This distribution is almost entirely due to the quality of the wind resource across the country.

This paper investigates costs and benefits associated with low-carbon economic development pathways realization to the mid XXI century. 30 scenarios covering practically all “visions of the future” were developed by several research groups based on scenario assumptions agreed upon in advance. It is shown that with a very high probability Russian energy-related GHG emissions will reach the peak before 2050, which will be at least 11% below the 1990 emission level. The height of the peak depends on portfolio of GHG emissions mitigation measures. Efforts to keep 2050 GHG emissions 25-30% below the 1990 level bring no GDP losses. GDP impact of deep GHG emission reduction - by 50% of the 1990 level - varies from plus 4% to minus 9%. Finally, very deep GHG emission reduction - by 80% - may bring GDP losses of over 10%.

The participation of household prosumers in wholesale electricity markets is very limited, considering the minimum participation limit imposed by most market participation rules. The generation capacity of households has been increasing since the installation of distributed generation from renewable sources in their facilities brings advantages for themselves and the system. Due to the growth of self-consumption, network operators have been putting aside the purchase of electricity from households, and there has been a reduction in the price of these transactions. This paper proposes an innovative model that uses the aggregation of households to reach the minimum limits of electricity volume needed to participate in the wholesale market. In this way, the Aggregator represents the community of households in market sales and purchases. An electricity transactions portfolio optimization model is proposed to enable the Aggregator reaching the decisions on which markets to participate to maximize the market negotiation outcomes, considering the day-ahead market, intra-day market, and retail market. A case study is presented, considering the Iberian wholesale electricity market and the Portuguese retail market. A community of 50 prosumers equipped with photovoltaic generators and individual storage systems is used to carry out the experiments. A cost reduction of 6–11% is achieved when the community of households buys and sells electricity in the wholesale market through the Aggregator.

When governments open up opportunities for private investment in traditional public sector areas, it is increasingly clear that a useful range of performance management information needs to be available to both government and business. Government needs to know how it is performing, comparatively, within and beyond its own domain, for the development of public policy and productivity enhancement. Business needs to know, understand and monitor the industry environment in which investment is contemplated or has already taken place. Performance measurement and monitoring is especially important where governments wish to attract foreign direct investment (FDI) to their shores. Whether governments manage performance and information well or are still constrained by bureaucratic and political thinking is still at issue. Using the example of the contrived national electricity market in Australia, this article, through literature and document review, examines the likely value to government and business of performance information, now available in the public domain. First, the article considers some of the changes to the Australian electricity industry. Second, specific performance indicators relevant to the national electricity market are examined in terms of their utility for government and business decision-making. Third, the impact of the political environment on performance management information is explored. The article concludes that while some important quantitative performance management information is available in a rational sense, other more political, qualitative indicators also need to be taken into account.
