The longest day

When the Sun aligns with the Tropic of Cancer every June 21, the Northern Hemisphere experiences its longest day of the year. This year, June 21 is not just an opportunity to enjoy this richness of daylight, but also an occasion to reflect on how we can best utilise the Sun's power.

On a bright, sunny day, the Sun's rays give off approximately 1,000 watts of energy per square meter of the planet's surface. Solar energy is clean and powerful.

The Sun is the source and sustenance of all natural life, as it provides light and energy. Our climate and weather systems are driven by heat energy that our planet absorbs from solar radiation. Solar-powered photosynthesis, in plants, on land and in the ocean, produces the oxygen in the Earth's atmosphere. These solar-powered life forms also provide the energetic base for all the food networks on the Earth's surface, including all of the food that humans consume. And then there are the Sun's many secondary benefits: its illuminating light for daytime vision, its ability to synthesise vitamin D in human skin, its capacity for generating clean, renewable energy to name just a few.

We see how reptiles bask in the morning sunlight, and how sunflowers bend to the arc of the Sun's path. Most of us have used solar-powered calculators, chargers and lamps; and maybe you've travelled in a solar-powered car, or even a solar aircraft. At the same time, we have grown quite aware of how intensive use of fossil fuels is endangering the lives of future generations. Thus the time to think about powering our homes, offices and other buildings with solar energy is right now!

Please join us in this effort and explore available options in your neighbourhood.

Print out the template, and then share a picture taken in front of a building or area that you think should be solar powered. Use the #putsolaronit hashtag, and upload it on either Facebook or Twitter.

The Regional Environmental Center is proud to announce that, following the 2013 Istanbul Climate Leaders Training, we established the Turkey and Central and Eastern Europe branch of the Climate Reality Project, an effort that raises global awareness to create a healthy, sustainable and prosperous future by making a global shift from fossil fuels to clean, renewable energies, such as solar and wind.
