Exceptional Engineering: The Making of a Wind Turbine | Engineering Documentary
Electricity harnessed from wind has become the second largest source of energy in Germany since 2017 – and has thus out powered nuclear and coal. Nearly 30,000 on- and off-shore wind turbines are operating throughout the country, covering approx. 19 percent of energy consumption. Our report follows the construction of a new wind power plant in Falkenthal in Brandenburg. Once installed, the windmill will be 179 meters high, supplying up to 5,000 households a year.

What It’s Like To Climb A 400-Feet Wind Turbine | Risky Business

Australian Renewable Energy Agency CEO Darren Miller told Sky News Australia has made “incredible progress” in the transition to renewable energy sources.

This comes after an International Energy Agency climate report set out a roadmap to net zero emissions by 2050 which suggested relatively wealthy countries should phase out coal-fired power plants by the end of the decade.

The report did not support calls for some states and federal politicians to continue investment in fossil fuels such as coal-fired power stations or Australia’s plans for a gas-fired recovery.

“The report is really saying what Australian is underway doing with our incredible progress we’ve made in renewable energy to date with almost 25 per cent of electricity coming from renewable sources now,” Mr Miller said.

“There’s sort of no stopping that transition because renewables are now the cheapest form of energy regeneration.

“We just need to figure out how to have that happen in a secure and reliable way as we balance the system and also as we turn our attention to the other parts of the economy outside of the electricity sector.

“It’s important to make progress on technologies to reduce those emissions too”.

Addresses the science of energy and energy efficiency and will include information on the factors that affect energy requirements including in depth information the science behind U-Values (comparison to R- values); Solar Heat Gain Co-efficient; low-E coatings; double glazing and triple glazing; effect of location and orientation on energy; shading etc.
Understanding the technology and testing comparisons will lead into the difference of upgrading windows, glass and selecting windows for a new build at the design stage. It will also educate on the limitations and effects on cost and will identify when and where fixtures and fittings such as awnings, screens and blinds integrate as systems for maximum benefit.
