The other day, my daughter asked me what time it was. I gazed up at the sun and told her it was 3:30 pm.  She checked her watch, and then in astonishment asked me how I knew the time.  She had no idea that you could tell time from the sun, even after we had just visited the Sundial Bridge and read the time from its cast shadows.  I was reminded of a project I used to do as part of a unit on solar energy when I was teaching K-8:  Human sundials.

To help children learn how the sun moves across the sky and how shadows are formed, the human sundial project takes a whole day.  First thing in the morning when the sun is up, go outside with your child and trace their shadow with some chalk.  Mark an X where your child is standing so they can return to the same spot.  Switch roles and have your child trace your shadow in a different spot. Then, return every hour and repeat tracing your shadows and recording the time on each shadow. By the end of the day, your child will see how their shadow moves in accordance with the sun’s path, as well as changes shape.

3TIER: one of the largest independent providers of wind, solar and hydro energy assessment and power forecasting worldwide announced the opening of an office in Bangalore, India today. It should be noted here that India is one of the top four wind-power markets in the world and also, the most developed market in Asia.

According to Kenneth Westrick, fonder and CEO of 3TIER, “India has the elements needed to prove that it is possible to leapfrog fossil fuels and fully integrate renewable energy projects into a country’s energy portfolio. He further elaborated on his statement by informing that India has good wind resources in its southern and western states, tremendous potential to tap into solar and hydropower, a government commitment to explore renewable energy sources and a market of more than 1 billion people – including 420 million people with no access to electricity.

Of the total number of villages in India with no access to electricity, it can said with absolute certainty that close to 40% of these cannot be electrified using fossil fuels. Thus, renewable energy sources such as wind, solar and hydropower can play an even greater role by electrifying remote parts of the country. “As the most densely populated country in the world with many villages that have no electricity, there is strong demand to augment the power grid in India,” said Steven Cashen, 3TIER’s Director of International Marketing Development. “3TIER will work closely with developers to assess and forecast potential wind, solar and hydro energy projects.” explained Cashen.

Top international environmental news for during the week of April 6 - 13:

Europe — World’s first commercial tidal turbine installed (EcoGeek)

“The world’s first commercial tidal turbine has been installed in its home in Northern Ireland’s Strangford Lough.

Though it has yet to be turned on, it will be the first commercial power-producing tidal generator when it is (sometime later this year). The turbine has two 16 meter-wide rotors and will be able to run for 18-20 hours a day. The turbine was installed off the coast in an area known for fast moving waters, and because the rotors will only spin 10-20 times in a minute, it is unlikely to disturb marine life.”

Africa — Tree-Nation (Tree-Nation)

“Tree-Nation is an ecological project with a focused objective: To plant 8 million trees in Niger, Africa to fight desertification! Large-scale plantation of trees will increase the land’s productivity and re-generate the soil.

Solar thermal energy plants focus the glare of the Sun’s rays on a central location to create heat, which is then turned into electricity. Various methods exist to concentrate the solar radiation, including parabolic troughs, power towers with mirrors that track the Sun (heliostats), parabolic dishes, and Fresnel reflectors. See a history of solar thermal energy.

For comparison with solar photovoltaics, see the world’s 13 biggest photovoltaic solar energy projects.

Maybe it’s because this national renewable energy company is based out of St. Louis that makes them so appealing to this St. Louisan. Maybe it’s the fact that I used to blog for these guys on their project blog and know that the folks behind the curtain are good people. Or maybe it’s just the way in which they do business. Solar Night Industries (SNI) would like everyone to adopt a modern (read: renewable) energy solution–it would be good for the planet as well as their bottom line. Yet, unlike many bottom-line focused companies, SNI wants their customers to be educated. They realize that not everyone can benefit from solar/wind energy systems. They also realize that the information regarding renewable energy solutions may be daunting to the average consumer. And, most importantly, they realize that everyone’s renewable energy needs are different. As a result, SNI has made the decision making process easy and informative for the consumer, through their Modern Energy Plan.

In Africa, the sun is abundant, yet traditional energy sources mostly derived from the local ecosystem like firewood and charcoal are getting depleted daily by a large measure.

The devastating aftermath of this depletion and its toll on the environment should call for another cheaper, plentiful and vastly accessible source of energy on the continent.

Solar cooking is now taking root in Africa more than ever before. Solar cooking projects are springing up on the continent mostly spearheaded by local cooperatives and non-profits working with rural women to assemble cheap solar cookers. Which works for environment.

If your trees are shading your neighbor’s solar panels, you could be fined $1,000 a day. The 1978 California Solar Shade Act deems shading trees a nuisance. In Sunnyvale, CA, Prius driving Carolynn Bissett and Richard Treanor were convicted under the law after electric car driving neighbor Mark Vargas complained .
