Energy price comparison websites play an important role in helping consumers to make informed decisions about switching energy supplier. In order to fulfil this role the websites must be trusted by consumers and be fully transparent about the service they provide. In the last year there has been growing criticism about the way in which some of these comparison websites operate. The Committee has been alarmed by suggestions that some comparison websites have been hiding the best deals from consumers by concealing tariffs from suppliers that do not pay the website a commission. The Committee concludes that all deals should be made available by default to the consumer and strongly objects to any attempt to lure consumers into choosing particular deals by the use of misleading language. The Committee also recommends that, as an immediate and essential first step towards rebuilding confidence, compensation should be provided to those consumers who were encouraged to switch to a tariff that was not the cheapest or most appropriate for their needs.

Smart meters, which allow energy suppliers to get remote electricity and gas readings from households and businesses using mobile phone-type signals and wireless technologies, should benefit customers through savings from energy usage and efficiency. In 2013 we first looked at the Government's programme to roll-out smart meters to 100% of UK homes and businesses by 2020. This inquiry reviewed the progress of the roll-out and we have been disappointed by the ongoing policy delivery challenges which the Government has failed to resolve: (i) Technical communication problems with multiple occupancy and tall buildings which should have been resolved by now; (ii) Compatibility problems between different suppliers and different meters; (iii) A slow start to full engagement with the public on meter installation and long-term use; (iv) A delay by the Government-appointed communications infrastructure company which has further set back confidence in the programme; (iv) A reluctance to improve transparency by publishing the Major Project Authority's assessments on the smart meter programme.

The Climate Change Act 2008 committed the UK to reduce its greenhouse gas emissions by at least 80 percent by 2050. The 2010-2015 Parliament has been a defining period for energy and climate change policy. Three Energy Acts set the policy framework to help the UK achieve its goal. Each Act was designed to support new forms of energy generation, promote energy efficiency and protect consumers. These ambitious pieces of legislation have set the benchmark against which the progress towards providing a secure, clean and affordable energy supply will be judged. The Energy and Climate Change Committee plays a central role in scrutinising and improving the Government's policy and legislation. In section two of this report, the Committee provides a quantitative overview of the work it has undertaken in this Parliament. In section three, the Committee looks in more detail at three case studies - electricity market reform, competition in the energy market and shale gas - each of which highlights the key role the Committee has played in holding the Government to account and improving policy and legislation. Finally, in section four the Committee sets out our future vision for the UK energy system, based on the views and evidence provided by the wide range of stakeholders that it works with. The Committee also explores the challenges which will need to be overcome in the next Parliament if the UK is to achieve its ambitious long-term climate and energy goals.

The transformation of vibrations into electric energy through the use of piezoelectric devices is an exciting and rapidly developing area of research with a widening range of applications constantly materialising. With Piezoelectric Energy Harvesting, world-leading researchers provide a timely and comprehensive coverage of the electromechanical modelling and applications of piezoelectric energy harvesters. They present principal modelling approaches, synthesizing fundamental material related to mechanical, aerospace, civil, electrical and materials engineering disciplines for vibration-based energy harvesting using piezoelectric transduction. Piezoelectric Energy Harvesting provides the first comprehensive treatment of distributed-parameter electromechanical modelling for piezoelectric energy harvesting with extensive case studies including experimental validations, and is the first book to address modelling of various forms of excitation in piezoelectric energy harvesting, ranging from airflow excitation to moving loads, thus ensuring its relevance to engineers in fields as disparate as aerospace engineering and civil engineering. Coverage includes: Analytical and approximate analytical distributed-parameter electromechanical models with illustrative theoretical case studies as well as extensive experimental validations Several problems of piezoelectric energy harvesting ranging from simple harmonic excitation to random vibrations Details of introducing and modelling piezoelectric coupling for various problems Modelling and exploiting nonlinear dynamics for performance enhancement, supported with experimental verifications Applications ranging from moving load excitation of slender bridges to airflow excitation of aeroelastic sections A review of standard nonlinear energy harvesting circuits with modelling aspects.

This study has emerged from an ongoing program of trilateral cooperation between WHO, WTO and WIPO. It responds to an increasing demand, particularly in developing countries, for strengthened capacity for informed policy-making in areas of intersection between health, trade and IP, focusing on access to and innovation of medicines and other medical technologies.
