If Green Energy Is So Great, Why Aren't We Using It?

Energy Efficiency No Comments »

Green energy is getting better and cheaper, yet we still largely rely on fossil fuels. Why haven’t we switched to solar and wind energy yet?

What Would Happen If We Burned All The Fossil Fuels On Earth?
http://www.popsci.com/burning-all-fossil-fuels-could-raise-sea-levels-by-200-feet
“A new study published today in Science Advances finds that if we burn all of the remaining fossil fuels on Earth, almost all of the ice in Antarctica will melt, potentially causing sea levels to rise by as much as 200 feet–enough to drown most major cities in the world.”

Who’s Winning The Battle To Replace Coal?
http://www.forbes.com/sites/thebakersinstitute/2016/05/17/whos-winning-the-battle-to-replace-coal/#e9dc97c6b09f
“Coal is losing the battle for the electricity future in the United States. Investment in new coal-fired generating capacity has dried up with its share of electricity generation dropping from 53% in 2000 to 34% in 2015.”

Electricity in the United States
http://www.eia.gov/energyexplained/index.cfm?page=electricity_in_the_United_States
“In 2015, coal was used for about 33% of the 4 trillion kilowatthours of electricity generated in the United States. In addition to being burned to heat water for steam, natural gas can also be burned to produce hot combustion gases that pass directly through a natural gas turbine, spinning the turbine’s blades to generate electricity.”

Environmentalists have long promoted renewable energy sources like solar panels and wind farms to save the climate. But what about when those technologies destroy the environment? In this provocative talk, Time Magazine “Hero of the Environment” and energy expert, Michael Shellenberger explains why solar and wind farms require so much land for mining and energy production, and an alternative path to saving both the climate and the natural environment. Michael Shellenberger is a Time Magazine Hero of the Environment and President of Environmental Progress, a research and policy organization. A lifelong environmentalist, Michael changed his mind about nuclear energy and has helped save enough nuclear reactors to prevent an increase in carbon emissions equivalent to adding more than 10 million cars to the road. He lives in Berkeley, California. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx

How will green energy change our future? What will our future look like with green energy? The growth of green energy goes together with change. Our future will not only include green energy, but our future will also be shaped by it.

What will the future sustainable world look like? That is the big question, now that the global transition towards sustainable energy is gaining momentum. For the growth of sustainable energy involves a lot more changes than just the color of the power supplied to our homes. How will we build, how will our mobility be impacted, and will energy, one day, be free? Just like the Internet turned out to have an unforeseen influence on all kinds of industries, from music to taxi businesses, the transition towards sustainable energy will also rise beyond the energy sector. And with a much wider impact than is now assumed. But we know surprisingly little about what that world will look like, and how the people in it will live, work and move around. Expectations are that, by the 2050s, two-thirds of the electricity generated globally will be sustainable.

The Netherlands is ambitious too. But what kind of world are we heading for, really, with all these sustainable measures? In partial areas, the future is clear: a massive stop to the use of gas, lots of windmills and solar panels, and perhaps a self-driving car outside. But, for now, there is no wider vision of what the sustainable new world will look like. What will the world be like once energy has become practically free? What will the impact of the transition towards sustainable energy be on the balance of power in the world?

A journey along places where the sustainable future is already (nearly) visible. In China, for example, old collapsed coal mines are given a new destination as solar parks. In Denmark, the power plants of the future also serve as skiing slopes. And in Malmö, Sweden, new leases are signed with green fingers.

Original title: Voorbij de groene horizon

With: Bjarke Ingels (architect, BIG Copenhagen), Peggy Liu (green pioneer JUCCCE Shanghai) and Varun Sivaram (author ‘Taming the Sun’ and expert clean energy technology Council on Foreign Relations in Washington DC).

How to design an energy efficient home

Energy Efficiency No Comments »

This week on the Green Building Show we continue our investigation into the energy efficient home. Carlos Martinez sits down with Steve King, a senior lecturer of architecture at the University of New South Wales, to find out the key drivers of energy efficiency within a home. Download “The Energy Efficient Home – the ultimate design guide” here: http://www.lighthome.com.au/green-guide-blog/the-energy-efficiency-home-the-ultimate-design-guide

We hear from Victoria Lea who brings us found some designers taking green living to a whole new level with a range of green jewelry, and we kick off our Tropical Housing Series with an interview with Peter Pierce, the designer of an award winning and sustainable tree house in Cairns.

And later, we will address a question from a reader who’s looking for a way to get her neighbors excited about solar. We speak with solar industry expert Ged McCarthy who presents us the business case for solar in a home.

BASF Video: Energy efficiency — The World in 2030

Energy Efficiency No Comments »

Energy efficiency is the most important single future source of energy to supply the growing energy demand and to protect the climate. Being energy efficient in industry, mobility and housing will offer the biggest potential to use energy more efficient. Just through energy efficiency and with already existing technologies it’s possible to curb our predicted increasing global energy demand and thus the CO2-emissions by the year 2030 significantly.

In this special video edition of our podcast “Chemistry of Innovations” you will learn how energy efficiency helps to protect the climate.

Insight Homes | Energy Efficiency: Ceiling Fans | http://www.itsjustabetterhouse.com

Building energy efficient homes in Delaware was the key goal when Insight Homes started. With that in mind we examined every single process and component that goes into home construction to see what could be improved, added or eliminated to make or homes the most energy efficient in the country. In this series of videos you’ll see how we raised the roof to improve insulation, provided for an endless supply of hot water, saved money on cooling and heating costs with customized windows and achieve the lowest HERS rating in the country.
