Further decreasing investment costs for PV, wind and electric storage expected: In this regard, the Agency for Renewable Energies (AEE) publishes a new meta-analysis today. It compares the investment costs reported in 15 studies for a total of 11 energy technologies, including offshore and onshore wind energy, photovoltaics and solar thermal energy.
Even after the EEG reform, most photovoltaic systems on buildings are economical to operate. sonnen GmbH from Wildpoldsried offers a "sonnenFlat". This is particularly interesting for those who already have a PV system and are thinking about adding a battery, but also for anyone planning to purchase a PV system in 2017.
In 2015, a historic double success was achieved for sustainability and climate policy. The 2030 Agenda for Sustainable Development with its Sustainable Development Goals (SDGs) and the Paris Agreement on climate protection define an ambitious global target system.
This is what the mayors of Mexico City, Paris, Athens and Madrid decided at the C40 meeting at a climate protection meeting of major international cities in Mexico City. They want to "do everything in their power to promote the use of electric and hybrid cars". In addition, more money is to be invested in expanding public transport and cycle paths [...].
In 2013, ABG FRANKFURT HOLDING built an apartment building with 17 residential units at Cordierstraße 4 in Frankfurt am Main as a passive house with energy gain in an existing neighbourhood. The specified orientation of the new replacement building, which is unfavourable for solar optimisation, posed particular challenges in achieving an energy surplus in the [...]
In 2012, the annual expansion in PV was still a good 7 GW; in 2016, it will reach just 1 GW. The expansion of PV in Germany has been falling for years and is now far below the government's expansion targets, which are already far too low.
The electricity for the electric car can come from the socket - or from the fuel cell. On the road, however, this technology is an absolute rarity. A car rental company in Munich now wants to change that.
The Paris Motor Show: Once again, the electric car is the focus of a major auto show. But the hoped-for breakthrough is still a long time coming. Cars with combustion engines should therefore pay higher fuel costs, says Florian Hacker of the Öko-Institut to the 3sat business magazine makro.
The new report of the International Energy Agency has it all: the power supply with renewable energies is growing faster than expected - and for the first time even faster than coal-fired power. An incredible turning point. Read the whole article: https://blog.campact.de/2016/11/rekordjahr-fuer-oekostrom-weltweit-sonne-und-wind-haengen-kohle-endlich-ab/
The Paris Climate Agreement has given renewable energies and energy efficiency a global tailwind. The Climate Protection Index 2017 presented today by Germanwatch shows a stable upward trend. Overall, however, the global energy transition is still proceeding too slowly to make its contribution to the Paris climate goals, warns the environment and development organisation Germanwatch. The choice of [...]
Since August 2016, fuel cell heating systems have been subsidised with an attractive grant of at least EUR 5,700 via the KfW programme "Energy-efficient construction and refurbishment - fuel cell grant". With a fuel cell heating system, electricity and heat can be generated simultaneously according to the principle of combined heat and power.
With efficiency, greater electrification and renewable energies it is possible to organise transport that is completely neutral in terms of greenhouse gases without having to accept any restrictions on growth and quality of life. This is the result of scenarios developed by the Öko-Institut and presented today in Berlin by Parliamentary State Secretary Rita Schwarzelühr-Sutter. The scenarios for greenhouse gas-neutral transport were developed jointly [...]
In September, Germany's largest thermal solar plant officially went into operation in the Brandenburg city of Senftenberg. The plant was built by Stadtwerke Senftenberg on an area of around 2.2 hectares and is expected to produce around four million kilowatt hours of heat per year.
Support for solar houses with large photovoltaic and solar thermal systems for heat, electricity and mobility remains constantly high "Solar houses with large photovoltaic and solar thermal systems for the climate-friendly generation of electricity and heat are not affected by the changes in the amended Renewable Energy Sources Act." Rainer Körner, 2nd chairman of the Sonnenhaus-Institut e.V., points this out. Since [...]
In Zurich on 30 November 2008, a 76 per cent majority voted in favour of reducing energy consumption to 2000 watts per capita by 2050. The average value in Switzerland is currently 6000 watts. The 2000-watt society has since been enshrined in the municipal code. "Particularly is before [...]
A film by French philosopher Philippe Simay on arte.tv In this episode, the philosopher visits the region of Vorarlberg in Austria, the international model for ecological and sustainable architecture.
They are highly efficient, low-emission and quiet: New fuel cell heating units generate heat and electrical energy as mini CHP units with over 90 percent efficiency. They have been tested extensively in detached and semi-detached houses, and their function and design have been improved step by step. The first systems are already on the market. They can be operated with natural gas as well as [...]
Vision 2020 The municipality of Wüstenrot wants to be energy self-sufficient by 2020. The project "EnVisaGe - Development of a municipal plus-energy concept using the example of the municipality of Wüstenrot" is part of the EnEff:Stadt initiative and describes how, in addition to reducing primary energy use and CO₂ emissions (keyword "decarbonisation"), independence from energy imports can be achieved and local value creation strengthened [...].
In the 2nd quarterly report on the development of renewable energies in Germany published by the Renewable Energies Statistics Working Group, it becomes clear that they are not growing as fast as in the previous year. The addition of photovoltaics fell from 614 megawatts in the first half of 2015 to only 514 megawatts in the current year [...]
For more than 180 days, the power supply of the almost 5 million inhabitants has been almost completely provided by renewable energy sources. Thanks above all to hydropower, the country can now almost completely dispense with fossil fuels for its electricity supply. In addition to hydroelectric power, wind power, photovoltaics and geothermal energy are also used. Source: www.trendsderzukunft.de/... [...]
The renovation project "Efficiency House Plus in Old Buildings" shows how two dilapidated rows of houses from the 1930s can be brought up to plus energy levels - and in some cases that good architecture can be created in the process. Read more on the DETAIL website
The EEG is supposed to achieve the goals of the Paris climate summit. But at the rate of expansion to date, according to a study by Berlin's HTW, we will have to wait until 2150 for Germany to switch completely to renewable energies.
In June 2016, the state government adopted a sustainability strategy for NRW. It is the first federal state to commit to implementing the global sustainability goals of the United Nations and has defined a system of targets and indicators for key areas of action.
