With the recent drop in costs for photovoltaics (PV) and the effect of dust and haze on solar-thermal technology(the technology originally planned) has caused a rethink in supplying energy to Masdar. The utilities management company has decided to use 50% photovoltaics and 50% solar thermal due to costs. Although photovoltaics produce 20% less energy than solar thermal they will cost 33% less to install. The use of solar power will cost more than 2.5 times the cost per kwh than the current method generating energy via natural gas.
Perth Airport is a vital part of the Western Australian and national economy.
In response to Perth’s growing need for modern, well-planned aviation infrastructure, the Master Plan sets out a ten-year, $2.4 billion investment program which includes the phased relocation of all regular passenger services to the International Precinct.
Perth Airport’s contribution to the WA economy is expected to reach $5 billion by 2029, with the number of direct and indirect jobs supported set to double to 37,000.
The fight for Montreal’s environmental future has recently reached new heights, as various environmental groups in the city promote the installation of energy-efficient green and white roofs.
Green rooftops, or rooftop gardens, are becoming more and more popular in Montreal, while white rooftops, flat surfaces with a white polymeric membrane stretched across, are just starting to be introduced.
The London Development Agency (LDA) has congratulated a London company that has been recognised for its innovative and environmentally-friendly approach to construction.
The company was recognised for its potential contribution to the engineering and construction industries at the London Technology Fund (LTF) Competition awards ceremony held on Wednesday night at the Royal Bank of Scotland’s head office. Sarah Ebanja, Deputy Chief Executive at the LDA presented the Environment Award to Novacem, a start-up company developing carbon-negative cement.
Novacem, a spin-out from Imperial College London, has developed a groundbreaking type of cement, which has the potential to transform the cement industry from being a significant emitter of CO2 to being an absorber of CO2. Novacem estimates that for every tonne of ordinary Portland cement replaced by Novacem cement, around 0.75 tonne of CO2 could be captured and stored indefinitely in construction products.
