You are on a discussion level of ten years ago.
All the questions you mention have been discussed for a full decade here. Numerous research institutes have been working on that for a decade. Several plans have been proposed and discussed. As a first step Germany has jump started its renewable energy industry a decade ago. We moved from 6 to 16% during that decade and now have several hundred thousand employees in that industry, numerous small and medium companies, numerous research institutes, ... we are already exporting a lot of that technology. It is expected that in a few years this industry will be larger than our automotive industry.
Our government actually does something for the tax payer money:

Renewables' contribution to energy supply in Germany continued to rise in 2010
17 percent share of electricity supply
370,000 employees in the sector
The share of renewable energies in Germany's electricity supply rose further in 2010. At 17 percent, the share was about half a percentage point higher than the previous year. These are the preliminary results calculated by the Working Group on Renewable Energy Statistics (AGEE-Stat) for the Federal Environment Ministry. This growth was achieved in spite of the sector being hampered by adverse weather conditions. As there was very little wind in 2010, the wind power yield of 36.5 billion kilowatt hours (KWh) was the lowest since 2006. Even so, wind energy remained the key pillar of renewables, with around a 6 percent share of the total electricity supply. Clear increases were recorded for electricity generation from biogas and the photovoltaic sector. Solar power almost doubled its contribution, covering around 2 percent of total electricity demand.
Current scenarios show that in just ten years, renewables can cover 40 percent of Germany's electricity supply. An increase of 12 terawatt hours (TWh) per year is considered realistic. (1 terawatt hour = 1 billion kWh).
The renewables' share in total final energy consumption for heat rose from 9.1 percent in 2009 to just under 10 percent in 2010. The renewables' share in fuel consumption rose slightly to an estimated 5.8 percent (2009: 5.5 percent).
Overall, in 2010 renewables covered around 11 percent of Germany's total final energy consumption for electricity, heat and fuels. This is significantly higher than the previous year (2009: 10.4 percent) and is remarkable because energy consumption was considerably higher than in 2009, due to both the economic recovery and the cold weather.
Renewables also increased their contribution to climate protection. In 2010, around 120 million tonnes of greenhouse gases were avoided through the use of renewable energies (2009: 111 million tonnes). Around 58 million tonnes of these savings can be attributed to the Renewable Energy Sources Act (EEG) alone.
The figures prove that renewable energies were able to keep pace with the economic recovery and continue their trend of a steadily growing share in our energy supply.
Alongside this, renewable energies also gained importance as an economic factor. Initial estimates for the BMU show that, at around 26 billion euros, investments in renewable energy installations were around one quarter higher than in 2009 (20.7 billion euros).
This development is reflected in the employment figures linked to the expansion of renewables. Last year, employment in renewables rose again and latest estimates show there are now around 370,000 jobs in the sector. This is an increase of around 8 percent compared to the previous year (around 339,500 jobs), and well over twice the number of jobs in 2004 (160,500).
