10 Ways To Save Money & Energy Using The Sun

solar_options_for_homeowners_infographic

One of the best ways to save money is also one of the greenest decisions we can make: that decision is the decision to save more energy. We waste a tremendous amount of energy in the US. Recent studies have found that we waste 61% to 84% of our energy in the US, and that we use 11 times more energy than the UK despite having only 5 times the population.

Energy is a huge portion of most people’s expenses. Cutting back just a bit on our energy usage could save money (tons of money) for all sorts of better things.

So, with all that on the table, what are the most effective ways to save money using the sun? I think all of the solar-related ways to save money (by saving energy) listed below are excellent solutions for the average American, but you can decide for yourself by evaluating the option as it applies to your own home or business.

Why Solar Is Far from Finished but Has Just Begun

Huge potential

In times of feed-in tariff cuts, there are many prophecies of doom for solar. Companies in different countries around the world have gone bankrupt and have had to shut down their factories. Reason enough for many to believe that the end is near. Not quite. Yes, in 2012 as the industry began consolidating, PV production recorded its first annual drop. But because demand continues to rise this contraction will be short-lived. Global solar developments show that this industry is far from finished but that the journey has only just begun.

From Grid Feed-in to Systematic Consideration of Grids: Challenges of the Energy Transition

In accordance with the Energy Concept 2020, the German Federal Government plans to generate over 35% of power from solar, wind and biomass sources. By 2050, 80% of electricity should be provided from renewable energy. The majority is to be provided by solar energy, which is fed into the utility grid by PV plants.

Accordingly, we are tackling the challenges associated with feeding PV energy into our distribution grids.

Vision 2050: A Look into the Past…

Ein-Blick-zurueck

It’s grey outside. It’s not quite that cold, but I’m freezing in my thin jacket. A winter without snow. The first in 20 years. I hurry through the dirty streets, looking at the black house walls. I find it hard to breathe—the air is thick. A desperate cry for help, begging someone to open the last lignite stockpiles. I see people everywhere, sitting there motionless, loitering. I feel uncomfortable, as if someone’s looking at my every move. It’s unusually quiet out on the streets. There are barely any cars. I look at a newspaper ad and read the headline: “No End to the Economic Crisis in Sight! Last Solar Energy Company Announces Relocation.” Three streets later, I look at a screen: “Energy Transition a Mistake: 10 Million Unemployed in Germany.”

Vision 2050: Full Supply with Renewable Energies

vision2050

The year is 2050. Wind energy and photovoltaics have been maximized to a performance of 300 gigawatts, and capacities continue to grow. Germany has become the first country to generate power without the use of fossil fuels, setting the bar for the rest of the world. This achievement is not only credited to a few larger companies  or to politics; each and every citizen played a part!

Vision 2050: Renewable Energy for Everyone?

Energien-Mix-2050

The energy transition. In the year 2050, it has become a reality. Our electricity and heat is produced exclusively from renewable sources. A crazy idea, or a realistic scenario? According to a current „Energy Revolution Report“, a complete transition to renewable sources is possible – if, as Greenpeace writes, the groundwork is laid now.

We have asked four German energy bloggers to sketch their personal vision for 2050. PV modules and wind turbine systems are integrated in homes so that they are almost invisible, and the banking sector revolution makes investments in sustainable projects, such as geothermal energy, possible. But more conservative perspectives for bioenergy are also represented. Happy reading.

Can We Still Afford Not to Use Photovoltaics?

Can We Still Afford Not to Use Photovoltaics?

What does the safe and clean energy supply of the future look like? How are we going to consume energy and how much is it going to cost? One thing is certain: Photovoltaics is set to be an elementary building block for the future of energy supply.

Change in perspective: d13 & energy revolution


Unreasonable? Unnecessary? Unimportant? – Not even close! Innovative? Democratic? Farsighted? – And how! It has been underscored by both dOCUMENTA (13) and the current public debate over the cost of the energy revolution: Contemporary art and renewable energies have more in common than you might think. For instance, both are frequently criticized despite the fact that contemporary art analysis and the possibilities of renewable energies are primary and indispensable investments in our planet. The underlying requirement here is always the same – you must be prepared to change your perspective and leave the well-worn paths behind – only then can you see the opportunities offered by new circumstances.

What Makes Wind and PV farms “Beautiful”?

Solaranlage_LET

Is energy compatible with art? That is the subject we have chosen for dOCUMENTA (13), the world’s largest contemporary art exhibit which is currently taking place in Kassel.  Antje Radcke, a blogger in the renewable energy sector, wrote an interesting post regarding the aesthetics of photovoltaic, wind energy and biomass systems. Thanks for the guest post.
