Wind energy has mushroomed into a mature and booming global green business while generation costs have fallen dramatically. Modern wind turbine technologies have been improved significantly in their power rating, efficiency and reliability. Global wind energy capacity is up to 196.6 GW at the end of 2010. This Chapter covers 1. mathematical models for wind turbines such as wind turbine (WT) with doubly fed induction generator (DFIG) and WT with direct-drive permanent magnet generator (DDPMG); 2. small signal stability analysis and nonlinear control using power electronic back-to-back converters, which are very similar to those of UPFC and VSC HVDC; 3. dynamic equivalent modeling of wind farms; 4. and wind farm interconnection with power grid via VSC HVDC link.

This report provides a baseline description of the transmission issues affecting geothermal technologies. The report begins with a comprehensive overview of the grid, how it is planned, how it is used, and how it is paid for. The report then overlays onto this 'big picture' three types of geothermal technologies: conventional hydrothermal systems; emerging technologies such as enhanced engineered geothermal systems (EGS) and geopressured geothermal; and geothermal co-production with existing oil and gas wells. Each category of geothermal technology has its own set of interconnection issues, and these are examined separately for each. The report draws conclusions about each technology's market affinities as defined by factors related to transmission and distribution infrastructure. It finishes with an assessment of selected markets with known geothermal potential, identifying those that offer the best prospects for near-term commercial development and for demonstration projects.

We conducted a vehicle analysis to assess the feasibility of thermoelectric technology for waste heat recovery and conversion to useful electrical power and found that eliminating the 500 W of electrical power generated by the alternator corresponded to about a 7increase in fuel economy (FE) for a small car and about 6for a full size truck. Electric power targets of 300 W were established for city and highway driving cycles for this project. We obtained critical vehicle level information for these driving cycles that enabled a highlevel design and performance analysis of radiator and exhaust gas thermoelectric subsystems for several potential vehicle platforms, and we identified the location and geometric envelopes of the radiator and exhaust gas thermoelectric subsystems. Based on this analysis, we selected the Chevrolet Suburban as the most suitable demonstration vehicle for this project. Our modeling and thermal analysis assessment of a radiator-based thermoelectric generator (TEG), however, revealed severe practical limitations.

This report documents trends in R and D and in particular (public) energy R and D in the Netherlands. Besides quantitative information on R and D and energy R  and D, the report gives an impression of changes in science and technology policy, energy policy and changes in energy research priorities (both organizational and financial). In the Netherlands, 2.09of GDP (or $6.7 billion)  was invested in R and D activities in 1995. The private sector financed 46of all  R and D in that year. A small but significant fraction (9.3) of the research performed in the Netherlands is financed by foreign public and private sector entities. Energy R and D has been identified by the national Strategic Foresight Activity as an important area of R and D for government support in the future. This is due in part to the overall decline in public support for energy R and D that occurred from 1985 to 1995. However, recent concern over climate change and energy policy has resulted in increased budgets for nergy R and D.

The electric power system is a crucial element of any mission for the human exploration of the Martian surface. The bulk of the power generated will be delivered to crew lifesupport systems, extravehicular activity suits, robotic vehicles, and predeployed in situ resource utilization (ISRU) equipment. In one mission scenario, before the crew departs for Mars, the ISRU plant operates for 435 days producing liquefied methane and oxygen for ascent-stage propellants and water for crew life support.

Security is not only relevant for the operation of the Smart Grid as a critical infrastructure but also very important for user acceptance. This especially affects domains like Smart Metering especially in the part of privacy issues. Many different standards exist in the IEC TC57 portfolio, among them standards especially designed for end-to-end security. Additionally international security standards like ISA 99 or the NERC CIP standards were developed and will be discussed here. Furthermore this chapter describes an overview on previous attacks in the energy domain, existing solutions and security standards, and also insights on security metrics and patterns.

There is increased recognition that geothermal energy resources are more widespread than previously thought, with potential for providing a significant amount of sustainable clean energy worldwide. Recent advances in drilling, completion, and production technology from the oil and gas industry can now be applied to unlock vast new geothermal resources, with some estimates for potential electricity generation from geothermal energy now on the order of 2 million megawatts. Terralog USA, in collaboration with the University of California, Irvine (UCI), are currently investigating advanced design concepts for paired horizontal well recirculation systems, optimally configured for geothermal energy recovery in permeable sedimentary and crystalline formations of varying structure and material properties. This two-year research project, funded by the US Department of Energy, includes combined efforts for: 1) Resource characterization; 2) Small and large scale laboratory investigations; 3) Numerical simulation at both the laboratory and field scale; and 4) Engineering feasibility studies and economic evaluations.
