Abstract The article analyses the implications of reduced subsidies for electric cars in Germany, to be implemented 2023. In addition high electricity price increases, rising costs lithium-ion batteries habe cut into incentive and will lead decreasing sales vehicles coming years. federal government’s objective have 15 million on Germany’s roads by 2030 therefore missed considerably.

In Part I of this article, we considered the technology and economics of alternative lighting systems, both electric and fuel based, demonstrating that there are ample and cost-effective opportunities for energy savings. In this second and final part, we consider some of the barriers that hinder the implementation of energy-efficient lighting. These barriers may be overcome by measures such as ...

Australia possesses the highest average solar radiation of any continent in the world, but solar energy in total contributes less than 1% to Australia’s primary energy consumption. This study intends to assess whether solar photovoltaic (PV) is really a sustainable option for Australia’s energy transition on the project level. A life cycle sustainability assessment (LCSA) was conducted on a 1.2...

This study aims to develop an economic evaluation method for installing photovoltaic power generation in ordinary homes using GIS (Geographic Information Systems). The conclusions can be summarized in the following three points: 1) This method determines the profit and loss and payback period in order to evaluate the installation of photovoltaic power generation, taking into account the price o...

Recently enacted state renewable portfolio standards (RPSs) collectively require that U.S. electricity generation by non-hydro renewables more than double by 2025. These goals are not certain to be met, however, because many RPSs apply cost caps that alter requirements if costs exceed targets. We analyze here the 2008 Illinois RPS, which is fairly typical, and find that at current electricity p...

Electric power systems are experiencing profound transformation driven by various factors. Bearing in mind the fact that most of today's electrical energy is produced using CO2 emitting fossil fuels, there is an obvious need to switch to renewable energy resources. Various new approaches under a 'Smart Gris umbrella' have thus emerged to tackle this problem. One of them is a so called Smart Hou...

Although early experiences indicate that the maturity of deployed technology might not be sufficient for operating wind farms in large scale far away from shore, the rapid development of offshore wind energy is in full progress. Driven by the demand of customers and the pressure to keep pace with competitors, offshore wind turbine manufacturers continuously develop larger wind turbines instead ...

In recent years various types of electric vehicles has gained again increasing attention as an environmentally benign technology in transport. Especially for urban areas with high local pollution this Zero-emission technology (at the point of use) is considered to provide proper solutions. Yet, the bad economics and the limited driving ranges are still major barriers for a broader market penetr...

Feed-in-Tariff (FiT) mechanisms have been important in boosting renewable energy, by providing a long-term guaranteed subsidy of the kWh-price, thus mitigating investment risks and enhancing the contribution of sustainable electricity. By ongoing PV development, the contribution of solar power increases exponentially. Within this significant potential, it is important for investors, operators, ...

The study presents a cost effective electricity generation portfolio for six island states for a 20-year period (2015–2035). The underlying concept investigates whether adding sizeable power capacities of renewable energy sources (RES) options could decrease the overall costs and contribute to a more sustainable, indigenous electricity generation at the same time. Often, island states rely on f...
