project linking solar power from the Sahara to energy users in Europe and North Africa could create 240,000 German jobs and generate 2 trillion euros ($2,822 billion) worth of power by 2050,executives from blue chip companies such as Siemens, E.ON, RWE and Switzerland's ABB along with firms from southern Europe and northern Africa will be at the inaugural meeting.

About 10 companies are expected to sign a memorandum of understanding setting up the Desertec Industrial Initiative.

Despite uncertainties associated with such vast multinational projects and concerns about political stability in the Mediterranean region, host Munich Re said the companies were eager to move forward with the next concrete steps.

"We believe the time is ripe for projects like this," said Alexander Mohanty, a Munich Re spokesman. "It's a great vision for the future. But we're not dreamers. This is the start of an industry initiative and we're looking for results.

"We're not just setting up a 'working group' to meet from time to time. The focus is on concrete results. The initiative will be doing lobby work, getting a dialogue going. The issue of the power price is important to be able to raise capital."

The European Union and German government are also firmly behind the projects. EU Commission President Jose Manuel Barroso and Chancellor Angela Merkel both expressly praised the idea behind Desertec at a recent Berlin meeting of energy executives.

Growing global efforts to slow climate change by reducing greenhouse gas emissions along with a projected increase in energy demand in the Middle East and northern Africa make the projects all the more attractive, its proponents say
