A Snapshot of Global PV 1992 / 2012 - IEA PVPS Programme

After several years of the PV market’s rapid growth, 2012 has been a year of market consolidation. In total, about 28.4 GW of PV capacity were installed in the IEA PVPS countries and the major other markets during 2012 (2011: 28.9 GW; 2010: 16.7 GW). This raised the total installed capacity in IEA PVPS countries close to 89.5 GW with another estimated 7 GW of capacity installed in other major countries.

The need and necessity of an EU-wide renewable energy target for 2030

In 2020, some leading EU energy and climate policies will expire. At present, the EU and its Member States are discussing the design of a post-2020 policy portfolio regarding greenhouse gas emissions and low-carbon energy. The central question is: which portfolio provides the most cost-efficient pathways towards a low-carbon energy system by 2050? This paper addresses the need and necessity of an EU-wide renewable energy target for 2030.

Heat Pumps for Larger Buildings

Heat pumps are increasingly being used in medium and large buildings to provide both heating and cooling. If specified and installed correctly they present a very good opportunity to save energy and reduce carbon emissions compared to traditional building heating and cooling technologies. This application note provides an overview of the types of heat pumps available along with the advantages and constraints of installing them in larger buildings.

The Challenge of Institutional Investment in Renewable Energy

A report by the Climate Policy Initiative

Institutional investors, which together manage assets of over $70 trillion, often have investment objectives that are aligned with the investment profile of infrastructure. At first glance, access to this large pool of capital and the alignment of objectives should help lower the costs of financing renewable energy.

Dual Wiring for Factories and Commercial Buildings

While having considered the energy saving opportunities by increasing the size of cables, Japan faced the urgent needs to save energy any possible way due to the aftermath of the Earthquake and Tsunami on March, 2011. “Dual Wiring” is the immediate solution without a large scale renovation or construction, yet to get the same result of cable upsizing. This paper talks about what is “Dual-Wiring” and theoretical study behind it.

Best Practices in Designing and Implementing Energy Efficiency Obligation Schemes

An energy efficiency obligation (EEO) is a regulatory mechanism that requires obligated parties to meet quantitative energy saving targets by delivering or procuring eligible energy savings produced by implementing approved end-use energy efficiency measures. The requirement to meet quantitative energy saving targets distinguishes EEOs from other similar mechanisms, such as a general requirement to acquire all cost effective energy efficiency with no target specified.

Standard EN 50160

Voltage characteristics of electricity supplied by public electricity networks

Standard EN 50160 should be understood as representing a compromise between the three parties which exert an influence on the power quality, i.e. network operator, network user, and manufacturer of equipment. Each of these three parties has an interest in playing their part. It is essential that electricity suppliers provide, as a minimum, a nominally adequate quality of supply.

The properties of LED lighting

Incandescent lamps are cheap but tend to have short lifetimes. The light emitted by incandescent sources is perceived as particularly pleasant because these hot radiators generate a continuous (or full) emission spectrum. Nevertheless, as hot radiators they waste much of the electrical energy supplied to them.

Spreading the Net: the Multiple Benefits of Energy Efficiency Improvements

Improving energy efficiency has long been advocated as a way to increase the productivity and sustainability of society, primarily through the delivery of energy savings. The impact of energy efficiency measures can go far beyond energy savings, and energy efficiency improvements can be an important contributor to economic growth and social development.

Nearly Zero-Energy Buildings and Offsite Renewables

The energy performance of buildings is key for reaching the European Union’s very ambitious climate targets. “Nearly zero energy building (nZEB)” is the term for a building standard that complies with this ambition. Living in 2013 we have 8 years to go until every single Member State will have to build every single new building as nearly zero energy building, and even only 6 years to go for nearly zero energy public buildings.
