nuclear power and solar power

The Japan nuclear crisis is giving the warning to all the countries , make people reconsider about the nuclear power safety. What should we do now?
Concern about the safety of nuclear power in the wake of Japan atomic disaster is triggering renewed investor interest in renewable energy such as wind and solar, sending share prices higher amid hopes for a fresh round of investments in the sector.
The troubles in Japan are set to imbue fresh life to an industry that struggled during the past two years as governments cut back subsidies during the economic crisis. But even as investors are coming back amid hopes for a spike in demand for renewable energy, industry insiders are skeptical of a global energy policy U-turn as solar and wind power are still expensive to produce.
The Renixx Renewable Energy Industrial Index, which includes the world's top 30 renewable energy firms such as Switzerland-based Meyer Burger Technology AG (MBTN.EB) and Germany-based SolarWorld AG (SWV.XE), rose around 10% since Friday when troubles at Japan's Fukushima Daiichi nuclear power plant became known.
Among the highest risers were U.S.-based SunPower Corp (SPWRB), which jumped almost 10% over the past few days, while Germany-based Q-Cells SE (QCE.XE) rose about 40%. Scandinavia-based renewables companies such as Green Wind Energy A/S (GW.KO), Arise Windpower AB (AWP.SK) and Vestas Wind Systems A/S (VWS.KO) also performed strongly.
"The disaster in Japan has already triggered decisions and discussion that show that a major change is under way," said Stefan Gaechter, analyst at brokerage Helvea in Zurich. "This will be positive in the longterm for the renewable energy sector."
Following the crisis at the Fukushima Daiichi plant, Germany decided to shutter seven nuclear reactors for three months and Switzerland suspended the approval process for three nuclear plants. Other governments have called for safety checks of existing nuclear plants and vowed to push renewable energy. The Chinese government Wednesday said it was suspending new nuclear project approvals.
But many governments remained adamant in their support for nuclear power technology, saying existing plants are safe and warning that shutdowns would burden the economy. While industry insiders expect demand for solar and wind to rise, fossil fuels and nuclear power will remain dominant energy sources, partly because of production costs and persistent government resistance to change the energy mix. Some analysts expect natural gas demand to rise sharply in the wake of the Japanese nuclear crisis.
Leif Jansson, spokesman for Arise Windpower, said the political shift should help renewables, but cautioned that "windpower will of course never be able to replace nuclear power, it will only be a component in a system."
Despite heavy subsidies, solar and wind power are still more expensive to produce than power from oil and nuclear facilities. Depending on which parameters are included in the calculations, electricity from solar and wind plants is twice as expensive as power from nuclear plants.
But the catastrophe in Japan has changed the outlook and investor interest is heating up again, said Thiemo Lang, fund manager at SAM Sustainable Asset Management, which has around $1 billion in renewable energy assets under management. The Japan situation "could bring about a sentiment change," he said.
"After the disasters in Chernobyl and the U.S, the renewable sector received a push as nuclear power couldn't be sold to the public anymore", Lang said. "A similar effect could play out in the wake of the catastrophe in Japan. This could lead to higher investments too."
Shares of Switzerland-based Edisun Power AG (ESUN.EB) soared nearly 40% this week amid hopes for more demand for solar installations in the company's key markets in Germany, Spain and Switzerland. "We hope that the recent decisions taken in Germany and Switzerland will bring about a paradigm change," said Chief Executive Mirjana Blume.
Investments have been limited over the past two years as many energy firms struggled to make ends meet. But efforts to curb greenhouse gas emissions have recently prompted large firms such as Siemens AG (SI) to lean more heavily towards the renewable sector.
On Wednesday Swiss power technology firm ABB Ltd (ABB) agreed to buy a 35% stake in German renewable energy equipment company Novatec Solar. Over the past few months the company has also invested in tidal energy projects in an attempt to spread out in other renewable energy fields.
Despite the renewed interest, chances that nuclear power will be dropped anytime soon is extremely unlikely even as political pressure around the world to get shut down plants is increasing, analysts said. According to the International Energy Agency, solar power only generated only about 0.06% of the world's energy, while nuclear plants generated 13.5%

So the solar power only generated about 0.06%? The
Solar panels conversion rate is too low, we should solve this problem from the root. Companies in China should take more effort to develop the technology for solar system, solar panel conversion rate, solar controllers efficient, solar converter.
Now we return to the start point, "Science and technology constitute a primary productive force" by Deng is always right.

Wuhanwellsee new energy industry co ltd as the branch company of hubei Bluelight science&Technology will put more funds to develop our technology on solar power and later on wind power and hybrid power. This is the bright way for company , for a safe world.
