As of 2007 plant construction and well drilling cost about €2–5 million per MW of electrical capacity, while the break-even price was 0.04–0.10 € per kW·h. [10] Enhanced geothermal systems tend to be on the high side of these ranges, with capital costs above $4 million per MW and break-even above $0.054 per kW·h.
In a statement, Merck said regulatory agencies have continued to conclude HPV vaccines are safe and effective, as have 30 years of research. Clinical trials have included over 70,000 people with ...
