Global Wind Power Capacity to Double by 2020

JBS News Renewable Energy.

Despite an overall slump in installations in 2013, the global cumulative wind power capacity will more than double from 319.6 Gigawatts (GW) at the end of 2013 to 678.5 GW by 2020, says research and consulting firm GlobalData.

The company’s latest report* states that China, the largest single wind power market, responsible for 45% of total global annual capacity additions in 2013, is expected to have a cumulative wind capacity of 239.7 GW by 2020. China overtook the US as the leading market for installations in 2010, when it added a massive 18.9 GW of wind capacity.

Are Perovskites the Future of Solar PV?

JBS News Renewable Energy.

A new material has entered the emerging low-cost photovoltaics arena and is threatening to blow much of the existing competition away.

Power conversion efficiencies (how efficiently incident sunlight is converted to electrical power) in perovskite-based solar cells have increased from a starting point of 3.8% in 2009 to a staggering 19.3% by May 2014.

This breakthrough is a useful spark for the emerging PV field, and the excitement is widespread that the editors of the journal Science selected perovskite-based solar cells as runner-up for Breakthrough of the Year 2013, and the journal Nature highlighted these materials in their summary of what’s in store for science in 2014.

US Electricity Sector Gets Downgrade From Barclays

JBS News Renewable Energy.

Barclays recently downgraded the U.S. electricity sector. That’s right, the whole sector.

It’s now listed as “underweight,” meaning that if you were to hold a full portfolio of bonds within the U.S. economy, you might want to be a bit light on U.S. electric utilities, as they might not keep up with the broader economic growth trends.

Why? One answer is the disruptive threat of solar-plus-battery systems.

A 36% renewable energy in the global energy mix is possible, affordable and helps mitigate climate change

The world faces an important energy choice, according to a new report launched by the International Renewable Energy Agency in New York today. “REmap 2030” says that scaling-up renewable energy to 36% of the world’s total final energy consumption by 2030 is possible, affordable and will keep the world on a trajectory consistent with a CO2 level of 450 ppm, the widely accepted threshold to limit global temperature increase to two degrees Celsius above pre-industrial levels by 2100.

ACORE The Outlook for Renewable Energy in America: 2014 (cover)

ACORE’s Outlook for Renewable Energy in America: 2014

JBS News Renewable Energy.

The American Council On Renewable Energy (ACORE) today announced the release of The Outlook for Renewable Energy in America: 2014, jointly authored by U.S. renewable energy trade associations from the power, thermal, and fuel sectors.

The Outlook assesses the renewable energy marketplace and forecasts the future of each renewable energy technology sector, from the perspectives of each of the associations, and provides a list of policy recommendations by the respective associations that would encourage continued industry growth.

The full (and fascinating) report is available for download in PDF format within the article.

Actual Distribution of Wealth in America

Wealth Distribution in America | Off the charts!

JBS News. Wealth Distribution in America is not what you think it is!

Watch this 6-minute video to see just how wrong our perceptions are about how the total wealth of the United States is shared between the different groups of people. “The Poor” and “The Middle Class” and “The Rich” are compared to “The Wealthy” in this video. What you will see is mind-blowing.

The total wealth of the United States (in 2009) was 54 Trillion dollars. Let’s see how that is distributed between all these different socio-economic groups, shall we?

The Home Battery System. Are we ready for this?

JBS News Renewable Energy. Home Battery Systems. Ever since lower priced solar panels have hit the market, it has become obvious that home battery systems are the next logical step for our modern, but still evolving, energy grid.

Installing solar panels on your rooftop has never been easier, as panel prices have fallen in price by 80% over the past two years and installation rebate programs are generous in many jurisdictions.

But getting all that free daytime energy from the Sun won’t do you much good unless you can store it for later use.

Having a home battery system allows you to store the energy that your solar panels collect every day.

Without a home battery system, solar power can make economic sense in many locations — but solar with a battery system will rock your world! OK, maybe not rock your world, but it makes a lot of sense if the battery system can be had for a reasonable price.

Without a home battery, you can still sell your excess solar generated electricity to the grid if your utility has a net-metering programme. But much of your profit is eaten up when you buy back some of that electricity after the Sun sets, at a higher price. Yes, every day of the year.

For homeowners, having battery storage means you could save a lot of money over ten or twenty years if a battery system is cost-effective to begin with — and, bonus! — a battery system IS a wonderful thing to have during utility company power outages.
