Clean energy is becoming attractive option to many homeowners and businesses. It is not just about going green and helping our environment as it also helps you save money, especially on the long run.

Solar energy is currently the most popular renewable energy source characterized by rapid growth in installation in almost every corner of the world. Getting the quality solar quotes online makes your switch to solar energy lot easier.

Most customers search for detailed quotes complete with technical information and pay back calculations. There are many variable taken into consideration prior to choosing your solar installer.

Basically, it is all about simplifying things as much as possible. The customers want quick, detailed quotes and professional information. Some people want everything from the most fundamental questions while others are very familiar with solar and look answers for some specific and complex questions.

There is almost a general consensus among the prominent environmental scientists about the urgent need for progressive climate policies with 97% of them blaming human activities for climate change. Sadly, the politics is still far away from what science suggests and globally speaking the world is still taking cosmetic measures rather than going for the full face surgery.

Helping our climate is not only environmental question, it is a vital social question. Heck, it's even a major economic question as according to recent paper published in Nature world would save more than $20 trillion by adopting progressive climate polices that would limit warming to 1.5 degrees Celsius above pre-industrial temperatures.

The researchers claim that current climate policies are inadequate and that they would only limit global warming to around 3-3.5 degrees Celsius. We can also forget about United States  leading the way because the current US policy is anything but capable to limit global warming effect and under president Trump America has showed zero ambition to curb carbon pollution.

Coal is fossil fuel that has many negative environmental impacts, and the most harmful of them all  is global warming driven by carbon emissions which are released into the atmosphere by human activities connected with coal burning.

The latest report from North Carolina State University and the University of Colorado says that from 2008 to 2013, coal usage decreased from about 50 percent of U.S. power generation to around 30 percent, which is news that is certainly well accepted by many environmentalists.

However, the downside of this news is that this rapid decline in coal usage is not primarily related with strict environmental regulations but rather with less expensive natural gas and the availability of wind energy.

Germany is second in terms of installed solar power capacity, trailing only global leader China. German solar industry experienced tremendous increase in installed power capacity in 2008-2012 period but since then the new solar power installations have been declining steadily.

But it looks like Germany's solar industry is back on track, this time characterized by steady and slower growth and not like in its prime years by meteoric rise in PV installations.

It is expected that German solar power capacity growth should reach the 2.5GW annual expansion target this year. A few years ago, Germany introduced subsidy degression dependent on capacity growth. As a result of this solar subsidies declined gradually, and in 2016 Germany decided to shift subsidies for solar installations above 750kW from a guaranteed payment model to competitive tenders.

Tidal power is renewable energy source that converts the energy of tides into electricity. Many areas in the world have constant and predictable tidal resources which can in turn lead to very efficient source of energy. However, tidal power technologies are still in infancy and in need of major evolution in order to become relevant in global energy supply.

Scientists estimate that about 80% of the energy from tides are located in areas of over 40 meters of depth, and this in combination with the current technological development leads to high construction costs. This is why tidal energy sector needs new technologies that are able to operate in areas where it is expensive to install first generation devices such as large structures held to the seabed.

Canada, and some European countries have already started testing first experimental parks based on devices set on the seabed, called of the first generation but lately there has also been talk about systems of the second generation which have anchors and a series of cables that hold the device to the seabed.
